Consider setting your rules to 'tag' as you roll it out...and change the tag field to be empty. That way your users don't see what is happening and you can check the message log to see what would have been blocked.
Make sure your port forwarding system still shows the originating IP address from the sending server to the Cuda for the connections. Not doing that will limit some of your abilities, or make things more difficult. I am sure it will, just pointing that out. Be careful what you classify as spam. Just because it is junk mail doesn't mean it is spam. If you classify too much legit marketing email as spam it will come back to haunt you. Also, it is far more important to classify Not Spam than Spam. Better to teach it what you want...that drives the score of what you want down towards zero making it easier to lower your block score. And last, do not send NDR's to the sender from the Bays blocking. Backscatter will get you in trouble pretty quickly.

The admin guide looks pretty straightforward for the various settings. Looking for any recommendations as to particular settings, lessons learned or gotchas as it were. We plan to start with inbound filtering, add outbound once that is stabilized. I plan to use port redirection and keep my current MX record unaltered, if that matters. Comments, suggestions appreciated.
