I would apply some thermal paste to the p4 heatspreader using a single edge razor blade or credit card. Less is better. Cover the surface with the thinnest possible layer. The $2 radio shack white paste works ok. Leave any thermal pad residue alone for warranty purposes. Read your owner's manual or the instructions that came with the heatsink to remove it. You have to unlock the 2 levers first, then use a regular screwdriver to separate the fan assembly from the motherboard bracket, one corner at a time, until all 4 are loose, and you can lift the heatsink off the cpu. Then move the lever that locks the cpu until it's straight up, and lift off the cpu. Be careful not to bend the cpu pins. To reinstall the heatsink, you have to engage all 4 corners of the fan assembly one at a time to the motherboard bracket, then move the 2 levers at the same time to lock it down.

1) No, not if you're carefull
2) If you keep the thermal pad oriented to it's original position on the sink, the material should go back into place just as it was originally
3) Ues the thermal pad
4) The Williamette was initially available in Socket 423, and later in Socket 478. Attaching the cooler would depend on which it is. The Intel cooler for Socket 478 is easy to install but a bit difficult to remove, I unlatch the top and use a pocket knife to pry the legs away from their engaging points.
