What I was interested in doing was to make it impossible for root to login directly, but rather enable other users to login and then su to root. So I edited /etc/ssh/sshd_config to read: #PermitRootLogin no (It was the dir I didn't know.) It initially said "yes", but it was

It's not going to have any effect unless you remove the # sign. You don't need to reboot, but do a 'service sshd restart'.
Please, *don't* restart the service. If you fuck up your sshd_config and you have no OOB remote access you're lost. `service sshd reload' is something more recommendable as it doesn't drop your current SSH sessions.
Just for the records: Another way would be to set PermitRootLogin to without-password and thus pinning it down to logins via ssh-keys only.
