Griff, thanks for trying to figure out where I'm going with this. To answer your question:
1 - Yes, but it's been awhile
2 - No
I'm with Mark on the small piece approach. Also Mark, your post of the PDF was very helpful. To answer Bill, I do use barre chords and just strike the higher strings, but due to arthritis, I can't play them for more than short periods of time (like 5 minutes). Also, there more than the 5th and 6th string root barre chord abbreviations to play triads. Also, what about chords like a minor 7th? A top three string abbreviation of a 6th string root barre chord is the same for a minor or a minor 7th. Do some chords require more than 3 notes? Sorry if these are dumb questions. I probably just need to learn some theory.
