No -- rehash only applies to tcsh(1)'s lookup cache of all of the
executables found on $PATH.

Yes, quite. Your login credentials are established when you login to
the system and only then -- that's when the limits of what you're
authorized to do are set, which includes amongst other things which
groups you're a member of. So you have to log out and back in again
to pick up any changes to /etc/master.passwd or /etc/group.
Cheers,
