Advice on Audio-Video connections on new H/T

I recently purchased the Pioneer 50" 5070 Plasma TV, Pioneer VSX-82TXS receiver, and switched from Dish Network to Comcast Cable with digital HD box. I also have a Pioneer CD player, RCA-VCR, Panamax Power center, and a Sony digital DVD player. I also just purchased the Vienna Acoustic Mozart towers and also the Vienna Acoustic Subson Subwoofer. I'd like to set this up with HDMI audio and video to the TV where sound comes through the "TV", for times I don't want or need sound coming through tower speakers through the receiver, and also have a connection through the receiver when I want for football games or DVD's... Any recommendations would be greatly appreciated. I'm getting mixed ideas and don't know which way is best. Thanks in advance.
