Read the Manual (V2.0)
I can tell you that one of the best sources of information I have had is the V2.0 manual.
The intro is very useful -- much improved from prior versions (V1.9 for example).
Also, know that everything to do with direct input and output via Stamp2 pins is more or less useless. You cannot use Pulsin or Freqout for example.
The basic structure of how you make a pin an input or an output is VERY useful (especially if you understand what the commands are doing to the variables INS, OUTS, and DIRS), but all but a handful of the commands that read from or write to pins are out of bounds because you don't have direct access to the pins of the Stamp2 from the RC controller.
Anyway, I recommend reading the book, especially the parts on how expressions are evaluated, how lines are parsed, and how math is performed internally.
Good luck.
