Hi list,
I'll answer my own questions. The following function seems to do the trick
of defining a local outline regexp for the minor mode in the current buffer
for me interactively. I don't know much Lisp yet but the Emacs wiki and
programming in Emacs lisp helped a lot.
(defun prompt-for-outline-regexp (new-regexp)
"ask the user for a local value of outline-regexp in this buffer"
(interactive "sOutline regexp: ")
(set (make-local-variable 'outline-regexp) new-regexp)
) ; defun
I bind it as follows:
(global-set-key (kbd "<f9>") 'prompt-for-outline-regexp)
And then, as to matching book headings, that one seems to be rather straight
forward, too. Here:

Quote with snippage:
For example, suppose you have a file that contains a book manuscript.
Chapters in this file always begin with a numbered title line, sections
beneath it are titled with the chapter number followed by a period and
section number, and subsections add another number, <snip>
You can view such a file as an outline in outline mode by changing the
outline-regexp variable to a regexp that will match one or more numbers
followed by the grouping of a period character and an optional second
number. <snip>
(setq outline-regexp "[0-9]+\\(\\.[0-9]+\\)*")
End quote.
