How do HDTV resolutions work, really?

I'm starting to do the research on buying an HDTV for later this year. Plasma/LCD/DLP/next-big-thing debates aside, I'm a little confused about the concept of "native resolution" and "upsampling".
I've seen HDTVs with resolutions of 1024x768, 1366x768, and of course true 1080p (1920x1080) (although my price range is currently below the 1080p level, which is why I'm more concerned).
1024x768 isn't 16x9, so how does that work? Does it look crappy?
Also, none of these have exact multiples of 480 lines, so how exactly does "480p" work (I've got a Wii and a regular DVD player, so this would probably be the most common mode I'd care about)? Does it show up in a smaller 480-line (or 960-line) box? Or does it squish/stretch/distort the picture in some way to fit it into the full screen of lines (in which case, how does that make it much better than an interlaced picture?)?
Or is "native resolution" really something that I don't need to worry about and probably wouldn't notice?
Looking for personal experience as much as technical answers. I hope that's not too chatfiltery :)
