New Plasma: 1080p or 750?

Right, I meant 720 not 750. Hmmmn, I've heard others say the same thing that, you can't really see the differnce between 1080p and 720 on a 42". but I really am not that in to tv and don't see a need for anything bigger. but just for arguments sake, how big of a tv do you need to see the difference between 1080 and 720?

I agree a quality 1080i/720p at a viewing distance up to 10' will look just as good as good 1080p. I bought a Pioneer Elite at a good discount when the 1080p's were just hitting and am hard pressed to see the difference when I see a 1080p. But when I get BluRay that may change.
I would say always invest a future proof as you can and get the 1080p anyway. I'd hate to deal with any regrets down the road.

But are you into films? Blu-ray into a 1080p display enables you to have a picture quality at home that exceeds the movie theater, and is sharp along the line of a full-resolution IMAX presentation.

In other words, if you see a 1080p Blu-ray feeding a 50" or larger 1080p display, you may change your mind about how important it is.

To answer your question, I think 42" is right on the cusp. With a Blu-ray 50GB source you'll notice the difference with a 47" display and definitely notice the difference with a 50" or larger.

All my life I've wanted to be able to afford the theater experience at home. Blu-ray into 1080p exceeds it.

It's a function of the screen size and viewing distance. I sit 15' away from 65" DLP RP, and I can't reliably distinguish 720p and 1080p. On a 42" display you'll need to sit real close to distinguish 720p and 1080p. I would guess no more than 5ft away.
