For example, I will start w/ my RH thumb on middle C, but then later on I will have to play up to the C on the higher octave, and go back and forth.
I think I need to be more skilled in knowing where the keys are without having to look.
Xvimbi, please elaborate more on the "body map" and "keyboard map". I have never heard of those terms, though I have relayed the meaning of them to students over the years many times. It's hard to tell a student not to look at their hands because when they ask 'why not', I can't think of a good reason other than "just because"! I mean, I look at my hands alot, but that is usually because I don't have the piece memorized yet.
