Well, those are all the light novels I've read so far, and I loved them all, so... =p
As for preferring the manga/anime adaptations, well, I generally prefer the original work over adaptations on principle, whether that original work be a manga, an anime, a light novel, or whatever, but in the case of light novels, I suppose there is something to be said for the visual effect a manga/anime can add, even if it does lose something from the original. I love the Haruhi anime, of course; it's very well-made, and heck, it's what led me to read the light novels in the first place. I tried checking out the Shana anime briefly after getting into the light novels, but wasn't too impressed with the execution or the way it screwed heavily around to the order/flow of events, so I never really watched much of that. The Index anime, I haven't checked out yet. But in general, the original is always best ^^
As for English works, well, I used to read a lot of books in general, mostly sci-fi, fantasy and the like, but I haven't really done much of that recently. (And by what standards are you classifying LotR as 'new'? XD)
