av123 has a fantastic deal ($1,500) on an X Series 5.0 setup that you would be hard pressed to beat at any price. All you might need is a sub but certainly not necessary.
You can can a Pioneer PDP-5020FD for just under $2,000... 50" plasma, fantastic set. Again, you will be hard pressed to beat this TV at any price.
As for a receiver any of the Denon line will do. The 2809 or 3808 are excellent choices.
The Oppo BDP-83 would be the last link in the chain and at about $600 you can't go wrong for a truly universal player.
That would put us around $5,500 if you buy new. That would leave plenty of room from a nice sub, cabling and whatever else you might want/need
You can also go the projector route and still end up well within your budget. Something like the Sony VPL-VW40 or VW10 and the Optoma HD80 would do well for projectors and a 100" screen from Elite Screens or DaLite would fit perfectly. A screen and projector would run about $3,500 tops.
