TV looks solid for the price, mine is the 650 series, so 1 step up but older.
Speakers I would go with the Polk monitor series, similar in price and they sound better. I think they still have some of the small Polks at best buy that you can listen to. I liked those little things more than any of the others they had in and the big ones are way nicer than that!

Reciever, I checked out Yamaha but they aren't real compatible with stuff. I did tons of research before I got my receiver on avsforum.com (killer place!).
New version of mine, just came out:

That is basically the same setup I have, if you ever want to hear it just let me know! I have a different sub, a 15" Cerwin Vega with 250w.
