Glenn Cook has a couple of terrific fantasy series.
The Black Company series tells the tale of a mercenary force that goes to work for the Bad Guys!
The Dread Empire series by Cook is another great one. Recently reprinted in two omnibus (multiple books in one) volumes.
The Garret novels. These are basically Film Noir fantasy novels, complete with a hard boiled detective, mob bosses and dames who mean trouble.
As much as I like Prattchet's stuff, they aren't necessarily a great choice for a non-native speaker since there's a lot of puns and "in-jokes". But you might still enjoy them. They are short for the most part and they could teach you a lot. I would try "Guards,Guards!" or "Small Gods" first.
David Webber has a fantasy trilogy out there. The first two books are terrific reads, the third isn't nearly as good though. The first two books are "Oath of Swords" and "The War God's Own". If you're inclined to try some science fiction, his Honor Harrington books are some of my favorite books ever written (they do start getting political in the last couple of books though). He's got a lot of other great Science Fiction novels as well.
Steven Brusts books are good, but do start getting political towards the end of the series. I can definitely recommend the first few books though. You should probably avoid the "Phoenix Guard" series, they're written as a fantasy version of "The Three/Four Musketeers" and have heavily archaic language.
Zelazny has another two book fantasy series. Changling and Madwand that I really liked. They are kind of old so you might have trouble tracking them down. Lord of Light by Zelazny is also a terrific book, it's based on Hindu Mythology and makes a nice change from all of the pseudo-medieval europe based fantasies.
While normally, I wouldn't recommend this, Terry Brooks "The Sword of Shannara" is him plagiarizing The Lord of the Rings, only in simpler language and without all the background. So it might be more suitable for you, yet still give you an idea of what Lord of the Rings is like. Then again you might be better off just watching the movies.
The first couple of Anita Blake Vampire hunter books by Laurrel K Hamilton are terrific. The later books start veering into bad porn though.
Larry Nivens has a couple of fantasy novels. One is "The Magic Goes Away". They aren't strictly speaking fantasy, but the Dream Park Novels are set in a Super-Disney Land/Live Action Roll Playing Game Park, where real people basically run through a "fantasy" adventure done with holograms and other special effects. Dream Park is the first Book. The California Voodoo Game is the third. The second books isn't that interesting, so I'd skip it.
The Myth-Adventures books by Robert Asprin are very funny. While there's a lot of puns, most of them aren't crucial to understanding the plot. There's also an absolutely terrific comic book adaptation of the first novel, that manages to be better than the book in every way. It was done by Phil Foglio

You might want to check out his Girl Genius web comic as well. It's "steampunk" or "gas light fantasy". Very funny and a great story over all

David Eddings "Belgariad" series is a great read.
