Would it be possible to copy and then setup/mod the Administrator group (calling it 'Moderators'), that I could add friends to, to be able to delete single photos, delete comments, move pictures from one album to another and primarily (most importantly) be able to approve new pictures -- without giving them permission to access the actual administrator control panel (config.php, usermgr.php, etc)?
No, this is not possible: there is no feature like "moderators" in coppermine yet, although it has been requested before. Please search before posting in the future.

I always search before posting...
Doesn't seem like a very difficult operation to me... maybe I'll just try it myself :-\\
it's impossible without heavy (extremely heavy) modifications all over the coppermine source code - the whole security concept is based on checking if a user is gallery admin or not. Just creating another group won't do you anything good.
