I'd recommend easypckits for sure. The premium kit sandpaper is amazing. Use 400grit of the normal SC stuff then use the premium kit stuff at 400grit. I don't quite understand why, but I start to get a better mirror finish in the lower grits better than with the normal SC stuff. Maybe Dave can explain the reasons why the premium stuff is better?
I've got a lapping guide in my sig if you want to read that. I've lapped 2 CPU heatsinks, a CPU IHS and a chipset HS... so it should give you a good idea on what to expect.
Most importantly you need to remember that you are looking for a FLAT surface, not a shiny one. If you can get both thats great but its better to have a dull flat surface than a shiny concave/vex surface. Use a flat surface to sand on and a flat surface to check against. I personally use a machinists ruler and hold it against the HS being lapped and hold it up to the light, if I can see light between the 2 then it is not flat and needs to be lapped more.
The benefits are lower temps and a nice copper mirror to admire yourself in while installing your CPU
