Well, you do need one or the other, but not both. Lots of folks around here will tell you that the compounds perform better than the thermal pads.
Your choice may affect your warranty, technically. Of course, <i>if</i> you can get the pad off cleanly and save it in case you have to send the CPU back, who's gonna know. Have you read yours? I haven't seen a retail Intel warranty lately, but I know AMD's talks about this.
Oh, and if you use the compound, don't use much. Just barely enough to cover with a thin layer.
