Thanks, J R and Georganna.
I set my title page as a separate file, and I also set the other three items I mentioned as separate files. That way, I can number each page any way I wish in the header. I also set each chapter as a separate file, and I again I can start the numbering any way I wish.
One more question, which is probably answered on the web site, but I’ll ask it anyway: I assume that the first page of each chapter should have a header and page number, even though in printed books it usually doesn’t?
