Tween or as fade

Hi

I was just wondering what kind of tween I should use if I want to tween the alpha of an object. I could of course use the old way by tween an object, but won’t take increase the size of the page?

And can you but alpha a png picture in flash? So I don’t have to make the picture vectore grafic.
