I've been involved in the tech industry since 2001 in varying capacities. I currently serve in operations for one a large cloud computing provider.
Great guide. I repasted my Early 2011 15" MBP with the 2.2 QC i7 and my peak load temp is now 87C (it was well over 100, and I was having it shutdown on me sometimes before). Having done this now, I must say I consider this system much more difficult to work inside than HP, Dell, or Lenovo/IBM laptops (having worked on all the others before). If you're patient, take it slow, and are careful though, everything works out. Here's some pictures of parts of the process:
