It's kind of difficult to recommend speakers to someone , for a whole slew of variables, let alone your particular taste, listening habits blah, blah.
Off the bat Klipsch speakers for me tend to sound bright as hell, and edgy ear fatigue is the only thing that comes to mind. Especially in the price range you're looking in, BUT that's just me. Plenty of folks around these part tend to love them, and if you have you’re heart set on a pair by all means don’t let this post hinder that!
Something I would do is concentrate on the front trio for now; like that you can stretch your budget a little longer, or get some cheap speakers for the rear until you can raise some cash for the what ever you want add for the surrounds.
I would say to listen to as many speakers at your price range as you can, check out EmpTek?, Ascend, Energy, Infinity, etc.
