Just purchased a new house with a living room about 30x30. Considering this setup with cost in mind, would like to stay in this range. Any advice appreciated.

Panasonic 50" Plasma HDTV (TH-50PX60U)

Pioneer VSX-1015TX
Polk Bookshelf Speakers Monitor 40 fronts
Polk Bookshelf Speakers Monitor 30 rears
Polk Center Channel Speaker CS1

PSW10BK / or PB10-ISD / or Veodyne

Also considered the Onkyo HT-S870

Need something clean to keep the wife happy.
