I don't know if I understand what you mean here... If "git diff p4/master.." gives output equivalent to what you would want to submit to p4, then that seems correct to me.

Well, I don't know gitg, but I can guess that it shows branches as blue if they are files created inside refs/remotes/*. This is the case for p4/master and p4/HEAD. They are placed there because normally, users should not update these refs, nor should they directly do checkouts of these branches (but your case is not exactly that normal).

git remote, shows remotes as defined in your .git/config file (the [remote "someremotename"] sections). git-p4 does not need nor create such entries.
