What's a good set-up for around $1000?

OK, I already have an Elemental Designs A3-300 sub, so the sub is not necessary in the price consideration. I also have a Pioneer Elite -21 reciever which I will most likely only use 5 of the avaliable 7 channels because of room design so I'll probably end up bi-amping the front two monitors. I want to get floorstanding towers and not bookshelves for these as well. I'd also like to use some bi-pole rear surrounds too. The room is 13L x 16W x 7.5H in my basement and is a dedicated HT room (movies only, no music listening). If my budget is unrealistic then please provide price estimates of your recommendations please.
