It's been said before, but congrats. I have sailed a Cat 22 from time to time and I learned early on to practice reefing. I always reef early, as I feel no embarrassment in taking the reef out if it turns out not to have been necessary.
My only other thought would be to make sure you are tethered to your boat. In the weather you sailed through, it sounds to me that should you go overboard, the other person on board was in no condition to perform a person overboard maneuver. And the last thing you want to see is the boat sailing away from you in such weather.
The Cat 22 is a good little boat, and your post-incident review seems pretty complete.
