no paste is used when the laptops are manufactured, and none should
really be necessary afterward.  it's true that later head spreaders
were modified (with an extra attachment point) to ensure proper
contact with the cpu, but you can help ensure the same thing by gently
bending each of the flat feet that holds a screw slightly downward. 
(not the ones that _don't_ hold a screw -- leave those flat.)  bending
the mounting tabs down will cause the center of the heat spreader to
bow towards the motherboard when the screws flatten out the feet.

there's a picture here:

if you're using the machine a lot, and you have the pennies, the difference
a faster card makes will be noticeable.
