You can run sshd in debug on port 22 if you're careful by killing of the
listening sshd first, which won't kill the existing sessions.  It's a good idea
to have out-of-band access to restart sshd if you make a mistake (or maybe an
"at" job or something).

No, you need to restart the main sshd that's listening on port 22.

You need to check wherever sshd and syslog are configured to send the sshd
messages to (this may be /var/log/authlog).  Check sshd's SyslogFacility option
and syslogd.conf.
