I would argue that Eddings Belgariad (what ever you think of it) was hugely influential.
It probably was influenced by Brooks but that is hard for me to weigh in on as I read The Sword of Shannara, and while it was OK I thought it was such a LotR rip that I never bothered reading more of his.
My loss?
1) Yes, Eddings' Belgariad was hugely influential to 1980's and 1990's fantasy writers doing secondary world fantasy and also highly bestselling from the very first book onwards. By the late 1980's, he had front of the store displays for the series and the Elenium sub-trilogy (1989-1991) was particularly huge. People tend to discount Eddings books nowadays because you are likely to find the reprints being sold in the YA section or shelved in YA at the libraries and/or the books are simply considered YA by many because the first part of the series started with a child/teen protagonist (though most of the books don't have a teen protagonist.) But the books weren't published as YA, but with Del Rey as part of Ballantine/Del Rey's launched (adult) fantasy lines. Back then three quarters of non-contemporary fantasy novels had teen protagonists (including Shannara). Adults read them without worry that they would seem childish doing so -- that wasn't really a thing in fantasy fandom until the late 1990's when YA fiction in general had its mega-growth expansion in the wake of Harry Potter. But for the period of 1982-1995, Eddings was huge and influential and certainly encouraged the idea of long, dynastic series, along with other big name writers like Mercedes Lackey. (He had planned to do the first story as a trilogy; Lester Del Rey needed the books -- all mass market paperback, not hardcover -- to be a certain size to work with the big chains and the paperback racks in the wholesale market and so made him cut it into five books of smaller size.) Numerous fantasy authors later on cited the series as a major influence.
2) Eddings was not influenced by Brooks at all. He noticed that Lord of the Rings was having a perennial reprint life in the category fantasy market and so sought to enter the market himself after having written several non-fantasy novels. He looked at the medieval epics he'd studied in college -- which Tolkien also drew from as a scholar of them. The main influence on the Belgariad is Malory's Le Morte d'Arthur -- the story of Arthur, and also Tennyson and Chaucer. (Of course, Tolkien also drew heavily on the tale of King Arthur -- Gandalf is Merlin, Aragorn is Arthur, the Fellowship on a quest is the Round Table knights, etc.) Eddings, who was also helped a great deal by his wife Leigh in the writing, wanted a story with a variety of cultures, major female characters and a grittier and less traditional and dated world set-up (where the Chaucer comes in.)
3) Shannara had LOTR leanings, but Brooks also was drawing from other epic fantasies of the time, D&D material, several science fiction novels of the time (leaning heavily into the idea of nuclear war mutations which Brooks placed alongside the magical race of elves/presence of magic) and Dumas' The Three Musketeers, which had a bigger influence over the series than LOTR. Shannara isn't really a LOTR rip-off -- it's a mish mash of various 1970's popular trends and isn't much different from many stories in the 1960's and 1970's. But Lester Del Rey chose Shannara to help kick off his new fantasy line/imprint and decided to market the book very heavily as Tolkien's heir, (even though it's a futuristic fantasy, not a sec world epic,) complete with an initial trade paperback edition to get more book reviews and library placement rather than just a mass market paperback.
That strategy, one which would kick off into overdrive in the 1990's for SFF when the mass market paperback market shrunk and they got more reliant on the bookstores, got the book more media attention in the 1970's but also a lot of backlash against Brooks. So Brooks' Shannara was a coattails book -- it hitting the NYTimes list hard helped fuel and fund a growth expansion for category fantasy (of all kinds) at Del Rey and otherwise by bringing in lots of readers, some of whom then browsed outward to other fantasy and SF books. But as an influence on other fantasy writers, Brooks' Shannara was not very influential. Writers weren't trying to copy Brooks; they didn't need to when they had Tolkien and other bestselling writers and sources who had much bigger thematic and stylistic impacts on secondary world fantasy and other sub-genres of fantasy.
Brooks' writing got more confident in the Shannara series and you can see the Musketeers influences more fully as the series goes on, as well as science fiction elements. However, it was his later Word & Void series (late 1990's) that was the one that was more of an influence on other fantasy writers and is often regarded as his best work as noted in this thread. The Word & Void trilogy is technically a prequel series to Shannara, set in present day Earth, but also worked as a standalone series (this is in keeping with how Stephen King connects many of his novels and King is the big influence on The Word & Void novels.) It is a dark fantasy series heavily influenced by King's Dark Tower series and other works and various other authors/influences and is very in keeping with the 1970's contemporary fantasy, dark fantasy and horror traditions. So you might like that one more, as others have suggested.
I read Jhereg by Brust back in the day. I remember liking it OK, but for whatever reason I never got around to reading more. I just picked up Taltos with the intent on trying in chronological order. My comment so far is the switching between present and flashbacks is jarring.
Brust's Vlad Taltos series was another big one, bestselling and deeply influential through the 1980's and 1990's, as was the side series set in the same universe, particularly The Phoenix Guards. I would suggest reading the Taltos series in the order in which it is published, rather than trying to read it chronologically. The books are mystery thrillers, partially episodic, following that tradition; Vlad is an assassin but also a detective/spy and each book in the series built on and was connected to the previous ones and their mysteries and incidents. So if you read them out of publication order, it is more confusing and you'll miss connective clues.
It's a favorite series of mine but it does go back and forth in time (which was a common technique throughout 1970's and 1980's fantasy fiction.) And you seem, from comments on some of the other books you've mentioned, to not like that type of story structure. So it might not work for you either way, publication order or chronological.

OK, will do - in the next day or two. Maybe a "history of fantasy" thread is in order, anyway, if only to come back to over time.
Well I was just talking about Shannara and related big cheeses, but if you want to do a bigger history thread, that's fine with me. Bear in mind, however, that thematic theories about fantasy fiction do not tend to hold up under actual historic publication facts and I am not being a meanie if I point that out.

I applaud Mostly H's suggestion of Jo Walton. I have barely tapped her TOR blog, but her What Makes This Book So Great & An Informal History of the Hugos each describe and profile the literature with commentary in lovely detail. As suggested, they focus more on SF (as did the Hugos) , but are excellent in describing what, when and how books were original.
Walton is good on history and insightful on analysis (and I like some of her fiction) but one grain of salt is that there are disputes over some of her opinions and interpretations (but when are there not.) But that series has been considered very informational.
