OK, Christopher. Posting the same thing in different forums multiple times is not endearing.
Call Axiom about what center and surrounds they recommend. They're very good about this, and generally do not oversell. I would probably go with the VP100 and QS4s in a room that size.
Reading through previous responses to your queries about Axiom vs. Klipsh, I would say that the Axioms are far superior to the Klipshes, although I have not heard either model in question.
12 gauge speaker wire should fit the bill.
A Hsu STF-2 or SVS PB1 should cover you as far a subs go. It's a fairly small space, so I doubt that you would need more than that.
