I'm afraid I can't speak to your 2nd and 3rd questions, but I can offer
what I think is a reasonable guess about the first.

One of the neat things about Unix and Unix-adjacent books of that era is
that very often the copyright page held some information about the
production of the book itself. I just so happened to have a copy of,
"Software Tools in Pascal" sitting on my desk, and it says, "This books as
set in Times Roman and Courier by the authors, using a Mergenthaler
Linotron 202 phototypesetter driven by a PDP-11/70 running the Unix
operating system."

Given the PDP-11 and the date (1981) one may reasonably conclude that it
was running 7th Edition. I imagine the pascal was Joy's, from Berkeley.
