I guess what I really want is a student study guide like we gave to ab-initio pilots in the RAF.
Well that book certainly exists
here.
However, can I suggest that what you might want to try - as an experienced aviator who can take material in rather faster (one hopes) than most student pilots, you consider acquiring an instructors guide?
The two I have, both excellent in their own ways are
and the much more recent Newton and Halstead: http://www.ontrackaviation.com/book.htm. For what you want, I think I'd pick the second.
Ultimately however, I still think you'll find sitting next to an experienced PPL doing a few burger runs will go a long way to helping it make a bit more sense. If you've associated yourself with a club, I'm sure they can recommend some of the good guys who wouldn't mind a passenger, particularly if you offer to chip in something for fuel and lunch.
