Let's answer the second question first. You might want to because you might want somebody to be a moderator in all of your 100 forums but one. It would be far easier to make them a Global Moderator and drop their permissions on that one forum than to give them moderator permissions for 99 forums.
As for the first question, I thought that I'd be able to assign somebody to the Global Moderator group, then edit that user's Moderator permissions for the forum that I didn't want them in and set them to Never. However, when I tried that, an interesting thing happened -- that person was now listed in the forum as a Moderator and in fact still had moderating powers. So the Never permissions didn't take effect. That seems like a bug to me (I should at least get an error message saying that I can't change Moderator permissions on a Global Moderator, I'd think).
However, that may give a workaround if you want Global Moderators to show up as moderators for a forum -- change one of their user moderator permissions. That doesn't appear to work if you try it on the Global Moderators group itself, though.
Ah, the wonders of phpBB permissions.
