In addition to the MPE/iX Shell and Utilities *Reference* manual
there is also an MPE/iX Shell and Utilities *User Guide* (as far
as I recall). The whole book is in tutorial style (as opposed to
reference) and the first few chapters can be quite handy (IMO).
Unfortunately, it does seem to only be available on paper, not
the LaserROM or Instant Information CD or the docs.hp.com site.

PS... I also seem to recall a paper or presentation on the Robelle
web site that was something like "HP-UX for MPE users" or similar,
which compared various commands/concepts of the two "worlds".
