Well yes I do!
Hot Topic sells a large portion of the "licensed movie" merchandise and it depends on if she's a movie fan or just the book fan or both (I'm both). They have very cool shirts, buttons, and all kinds of other stuff that are awesome (the Edward Cullen sparkly powder would win over any fan and make them squeal)

A cool gift might be the collectors edition book (its signed and has torn pages, a really cool cover, and lots of other stuff). Or pre-order the movie for her and put the receipt and a print out of the picture of the movie (I can get you the picture of the movie cover)
cafepress has over 14,000 Twilight items, including mugs, shirts, coasters, buttons,
oh and SEARCH EBAY!! You could get a haul there for cheap
Get her the soundtrack if she doesnt have it
Borders has some exclusive Twilight stuff too
what about the audio books?
If she's into the movie, get the Illustrated Movie Companion (Very cool) and then preorder her the book coming out by Catherine Hardwick which is notes from the director while on set
Or preorder the book by Stephenie Meyer coming out, the official GUIDE to Twilight
