It's better English than many native English speakers on the internet can do.

How do you go about practicing something like this? Obviously learn the individual parts, but do you chunk two at a time and add on the third later, or do you just roll through slowly with all the voices?

That arm better be nuclear-capable real soon or we might have to riot.

Us music majors would just get reallg nervous watching it.

But really, music theory would be nice, but it depends on his level of expertise in music. Music theory is a very deep and popular field of study, people get Masters and Doctorates in it. The question is, how deep do you go? Do you just talk about instrumentation, major/minor chords, general mood, and so on; or do you get into form, harmonic analysis, musical devices, etc. If he doesn't know very much of that then it might not be a good fit.

I'd definitely think that maybe a Book or Literature Theory would be really cool as it's another major form of popular media that isn't covered.

Indeed.
