Thanks for your input, it's much appreciated.
I've disassembled plenty of laptops in the past, but never a Macbook. My previous place of employment always assigned Macbook disassembles to my other co-worker, since he had plenty of experience. What do I need to know in advance before I start following these instructions "to-the-T"?

I'd add Remove fake antivirus to that list. It's the best thing that I have found for removing thise fake phishing tools that show up on windows from time to time.
Well, in terms of software itself, I can't think of what programs you would use off the top of my head.
Hardware wise, I know what I'd probably do. Primarily, I'd figure out what the best program to do this with is, but that's probably on Andrew's USB Fixit stick. I wouldn't let the harddrives run any more until after you've done the freezer trick.
After you've done the freezer trick, I'd put 'em on an external bay and see if you can extract any of that information, and try and get as much data as you can as quickly as possible.
You can find out the license number of the Windows machine you're on by using a freeware program, such as the Magic Jelly Bean Keyfinder http://www.magicaljellybean.com/keyfinder/ Usually this works for me, do neither of your laptops have stickers with readable Windows COA's? It's a problem I run into at work all the time.
