Thermal paste is only used to transfer heat more efficiently between the two surfaces. You ask "how much". Make sure your heatsink does not already contain paste on the bottom. If no paste is present then determine the size of the processor. You will want to apply a very thin layer. You do not want to apply to much because when you bolt on the heatsink it will squish out the sides. I would say about 1/2 the size of a tic tac and smooth it out. if it seems to be too much then wipe some of it off.

Copper paste is conductive so be careful not to put too much on. It could short circuit if it was in the wrong place. Yes you can use copper paste on aluminum .... it doesn't matter.
