First time upgrading - Need help with heat sink and paste

Hi Tom's,

I'm going to be upgrading my older tower in two weeks. This will be my first time doing this myself, and I'm a bit intimidated by heat sink and thermal paste. From what I can see, even seasoned computer builders have trouble with some of these parts, as the instructions for them are supposedly worthless. For a newbie like me, that sounds like a death-sentence.

These are the parts I will be getting:

I've put in my own GPU and PSU before, so I'm not worried about that. Mainly it's just the heat sink and the compound...possibly setting the processor in too, but from what I read it shouldn't be too complicated.

Now, I have been on the AS5 website, and found the instructions here: "http://www.arcticsilver.com/pdf/appmeth/int/vl/intel_ap...". However, it mentioned that it could be different depending on the heat sink. Can someone confirm that these instructions are good for me?

And as for the heat sink itself, the reviews I read on NewEgg mention the instructions are just crap. So is there any tutorials or other instructions anyone can recommend to me? Or if anyone has used the same product before, can you walk me through it?

I really appreciate everyone's help. This forum has already helped me with several issues, and I'm hoping to get my first project tower up and running by April. In the mean time, I'm just going to focus on upgrading this tower first. Thanks everyone!
