What "priming" thing? (probably not.)
when you clean it off, use a bit of rubbing alcohol (90% or higher Isopropyl) to make sure you have gotten ALL of the old paste off. Never ever ever reuse thermal paste.
just put one rice/BB sized dot on the CPU, and attach the heatsink, the pressure will flatten out the paste. If you use your finger to smooth it out you can create air bubbles which is bad for temps.
And remember, less is better for thermal paste. its only supposed to fill in the tiny gap between the CPU and heatsink (and the impurities in each surface).
And like other people said, be extremely careful that you get all four pins/locks set properly for the mounting, since they can be somewhat tricky, and if they are not all the way in, you will get terrible temps since the heatsink is not making complete contact.
