Hey Chris, you wrote above:

"For now, as a beginner, it's enough to know that one pentatonic box shape & work on making music with it."

I'm really glad you said that. For some reason, I was getting wrapped up with trying to go up and down the neck as a beginner. Seems stupid in retrospect. Anders said something that compliments what you said. Something like, "Limitation fuels creativity", then went on to demonstrate that by playing some awesome sounding improvised blues riffs over a backing track... using just 3 notes.

Your advise about staying in one pentatonic box must be constraining for advanced guitarists, but it's liberating for beginners like me. Thanks!
