Answer 1

If you have the time, I would advise you to watch this lecture: http://www.youtube.com/watch?v=KHpjLeKtKw0&feature=relmfu
There are some concepts that aren't taught in 6.00, like ADTs, and stuff like that, but it is very much comprehensible even without prior knowledge on the subject :-)

Answer 2
