getting rid of a zit in a clip, lol...
 

ok, weird question here but I guess it's something I need to learn. working on a video for some folks (wife's relatives) and I have a quick clip of one of the girl's backs that i set to a black and white image. well you can see a spot on the back of her shoulder at which my wife said is a big zit and sure enough in color and zooming it does look like a big zit. so rather than just delete the clip I'd like to learn how to fix it. what tool in pp2 would let me say take another small spot on her back and copy that color over the zit so you cant see it? or is there a better way for fixing blemishes such as this?

I´m not sure in Premiere.
In After Effects you can use the clone stamp tool.
May be if you put a second version of the same track over and use the crop effect and move that layer so it overlaps the area you want to cover, but that depends on the shape of the area.
Another possibility is to export the clip as filmstrip and then open in photoshop, duplicate the layer, make a selection around the area you want to work, move the selection to an area as close to the original area you want to cover (to try to get the same color and shades), ivert the selection, put some feather and erase. Now move that layer to cover the area you want to fix. Collapse the layer, save and you are done.
Only some ideas to try.
