Yes, the imap(s) ports on the slave are closed for public access behind
a firewall. Users can't access the replica directly.

On both sides; an "unexpunge -l" on master and slave shows exactly the
same number of deleted files in the INBOX.

Yes. I run nagios and monit checks on the /var/lib/cyrus/sync/log file.
If it exists and increase above a specific size I get warned.
