I am not sure how many people on the list will have time to answer all
your questions.

For me, you are asking too many questions in one posting.  In addition,
I think that you can find many of the answers to your questions by
reading the Slurm documentation, in particular the man pages for the
individual commands (e.g. see 'man acctmgr' for information about
setting up users and assigning them to accounts).

If you then encounter a specific problem, write to the list saying what
you tried and what error you got.
