1. i see a lot of tvs offering one or the other, which one is better in terms of image quality?
2. i have a regular tv, it's like 29" CRT kinda tv, no HD or anything, would it support a component cable or it would just have composite switches?

1) Wait for 1080p, 1080i isn't all it's cracked up to be, and 1080p will really only be noticeable on large (>50") screens when compared to 720p.

2) look on the back for component inputs. They're usually red blue and green RCA's and labeled "Y Cr Cb" or "Y Pr Pb".

1080P sets are considerably more expensive compared to 720P sets.

which is why I said wait. Apparently his budget isn't roomie enough for a 1080p set, but the prices will come down and he can save some more money up and get something a good bit nicer compared to what he can get now. Plus things seem to be moving towards 1080p anyway. It would suck for him to get a 720p set now and then in a year everything be 1080p. Then his 720p set would have to downscale the 1080p source and make it look like ass compared to true 720p sources.

i see white, yellow and black for the inputs on the back of my tv, what's that mean?

also, i assume 720p is better than 1080i then? is progressive THAT much better than progressive?

a 42" can that handle 1080p?

white = left audio channel
black = right audio channel
yellow = composite video

I think you mean is progressive that much better than interlace. Answer YES. Interlace only spends half the image per frame interlacing the lines that make up those images. So you're essentially getting a 540 line resolution for 1080i and 240 lines for 480i.
 
also, i notice a lot of 42" plasmas have 1080i support, but only have up to 1024x768 max resolution, doesn't the 1080i imply 1900x1080 resolution?

it downscales and deinterlaces. And depending on the set, it may look okay, or it may look like shit. And if you're going to go that route make sure the panel has at least 1366x768. Most 1024x768 panels I've seen don't look so hot even with 720p sources. (It has to scale the 1280x720 to 1024x768)

i thought when a tv has 720p or 480p or whatever that it would be at that resolution, where is this 768 stuff coming from? like 1366x768, isn't it just supposed to be 1280x720?
