Need help with a couple small things for PS CS

1) Is there any way to select an area in one layer, then move to another and have that area still be selected? As in, I select a blue shape in layer 1 and then I can cut out a matching one in layer 2?

2) When drawing preset objects like rectangles or polygons, is there a good way to make the edges *sharp*? I often use templates for icons, and make them this way, but they always seem to have grey "halos" that look kind of ugly.

And re: the above, is there any way to make polygons of a set size? Or copy one you've already drawn?

Finally, for bonus points - can anyone suggest a place to look for the "Coca Cola font"?
