If I could go back and teach myself commutators, I think I would say this:
Play with [R*:U,M*] and [U*:R,D*] (where * means regular or ' or 2), until you're familiar with the shapes of all of those possibilities and understand why they do what they do. Then invert and mirror and rotate. Then start solving the cube 2 pieces at a time, using setups where necessary. Then check different lists to see if you've missed anything.
I'm not saying that's the only way or the best way, but I think it's how I'd like to have had it presented to me. (I wound up writing a program to categorize all the cases on the BH list instead. It was a fun project, but more work than most people probably would want to do).

If I keep up this pace, though, I should know all 378 by June 15th, and I give myself until the 22nd to practice like crazy because I need these BLD skills by the 23rd. xD
