Also, he lost me way up top when he drew a line across the circle and didn't know what chord went there, but did know the two on either side.

Must say I thought he was making life unnecsarily difficult there. Why not just draw your circle with twelve points, Write C at the top and then write in the fifths in order clockwise? To work out what the next fifth is, write out the chromatic scale and count up seven semitones.
