grats on the new tv.
With LCD, theres no worry about burn-in. You could watch fullscreen content on it (black mattes on the sides) all day without worry.
One thing which I have seen with practically every LCD based display is a few pixels become dead within the first week of viewing so don't be alarmed if you see some pixels stuck on a certain color. From proper viewing distances, (even if you know where the pixel is) it is impossible to see or point out. Also they in no way interfere with overall picture performance.
1080p nice. My eyes are used to a 60" display so on one of my tv tests, I decided to try a 46" display. Gave me headaches within only an hour. Funny thing is this happens if you go from a smaller to larger set as well. If your previous tv was around the same size (42) than I wouldn't worry about that. I'd first turn the contrast & brightness way down. Them factory settings are killer.
Enjoy your new HDTV.
