I was thinking of having a header and a footer fit on almost any resolutions except the really small ones... now i was thinking of doing this by using a stretching point and making it 100% but it doesnt seem to work for some reason is there an other way?

In what way doesn't it work?
I've done themes that are fixed width, and others that stretch to fit screen resolution, either way is not that difficult.
I've also done a theme that has 2 versions depending on screen resolution - it uses javascript to sense the user's resolution, then directs to the appropriate style sheet. I have one for 800 x 600 and under, another for over 800 x 600. These are both fixed width. There's nothing to stop you from specifying more sizes.
