Answer 1

Dave is right. This can't really be automated (at least not in ID).
The last time I ran into a book like this I *thought* I could automate it by using running head variables and picking up an invisible autonumbered head in the text flow. I was disappointed to learn that variables don't "see" the autonumbers.
I ended up converting all my autonumbered section numbers to actual numbers. So at least they went into the running head automatically once. But if I had had to add or remove a section I would have had some typing to do.
