Daimbert, no criticism intended here, but you do seem a bit befuddled, and I'm not sure a dozen more posts recommending different speakers is going to solve that problem. So my first suggestion is to stop asking for advice and get out and listen to some speakers. Start to figure out what you like, rather than worrying about what everybody else likes. When you pin things down a little, you can come back here and ask some more specific questions.
On the bookshelf vs. floorstander question, my advice is to go with the bookshelf. (Yes, you'll need stands, but you don't need to spend an arm and a leg for these. Just look for something stable.) I don't think there are too many good floorstanders in your price range. You're buying more bass, but not necessarily a lot more bass, and probably not better bass. I prefer a speaker that doesn't try to do everything, because it's more likely to do most things right.
Something like the Paradigm Monitor 3 or the PSB Image B25 or the Infinity Beta 20 might suit you. All run in the $400-500 range. I suggest you check their websites to find dealers in your area.
