By the time you purchase decent stands for the bookshelf speakers, you are usually with in a few hundred dollars of the floorstanders. Knowing what furniture will be in the room is just as important. The height of the speakers relative to your listening position should be factored into your speaker selection. Bookshelf vs Floorstanders for home theater is more about preference than anything. Most speakers need the support of a decent subwoofer to be effective at home theater duties. There are hundreds of speakers that we can recommend, but your better off going out and listening to some of them first.
I'd personally rather have floorstanders with a sub than bookshelf speakers with a sub. I'd rather have certain floor standers without a sub than bookshelf speakers with a sub.
There are nice folks on this forum who will offer different opinions and they will be valid opinions. I don't mind the floor space a full size speaker takes (I've got some large speakers). My subs are huge, something approaching 4 feet by 5 feet by 18 inches deep. I don't mind those either, they make a nice place to set extra hats when they're not being worn.
It's all a matter of trade-offs and priorities (in my opinion)
RTi A7 $800 (polk ebay store)
CSi A6 $300 (polk ebay store)
RTi A3 $200 (polk ebay store)
Dual PC12-NSD cylinders $1399 (http://www.svsound.com)

I have never been a fan of polk audio. I find their tweeter bright and fatiguing. With that said quite a few people like them the A7 and A9 are your best bet. I dont know if i eould jump on a separate amp. It gives you more headroom and lower distortion however you dont realize those gains unless you push the speakers. If you do tend to test their limits then it might be worth the investment.
Svs makes some very nice subs. Rythmik also makes very nice subs. For $700-800 i think PSA offers the most value. They have 15" ported and sealed designs that compete with much more expensive units.
