I'd recommend this:

Lots of great reviews and honest commentary about what specs matter, and which ones don't.
A lot of the reviews of plasmas and LCDs on this site stressed the idea that 1080p is really not too important until your TV starts getting REALLY Big, like more than 42". And, hardly anything is supporting 1080p yet, (except for some of your games), and blu-ray, but don't even get me started on that crap.
If you're willing to pay a lot more NOW to get the 1080p it's certainly a fine choich, especially in a year or two when broadcast TV and (everything except games) catch up with it.
