Im surprised nobody else suggested this, but:
Get a padlock or really any pin tumbler that you do not need to use, and then just disassemble it and look at how it functions. you wont need much mechanical knowledge to attack a padlock with an angle grinder/dremel, right? Sometimes just looking at things and being able to feel and see what they are doing is better than looking at PDF's on the internet. Still download/read the MIT Guide though, because its got most of the fundamental things you'll need to know in order to have success.
Hope that helps.
