Go LCD, and go all out. 1080p. Not 720p, not 1080i. Make sure it has at least 2 HDMI ports. and like 2 or 3 Component ports, and all kinds of other in-ports, so you can hook up your Blu-ray, Wii, PS3, Cable Box, digital camera/camcorder, Bose surround sound, Dvd, VCR, etc etc etc.

And shop around. Don't just walk into Bestbuy and get hosed. Check independent stores too.
Check Consumer Reports. A $50 subscription may save you $1000.

Make sure you save your receipt, because my Sony took a crap after about 9 months and even with the receipt, they were a pain in the ass to deal with to honor their warranty, and I had to drag it across the county to a "certified repair facility." I'm done with Sony because of that. Also the repair guys warned me that if anything else ever went wrong and I had to pay out of pocket, it would cost me more to fix than a the price of a new set. We also have a Samsung in the other room. When it started making a funny noise they SENT OUT a repairman the next day. Quite a difference in product support if you ask me.
