I'm so happy for you and your hubby. Isn't it amazing how it can all come back together?
My advice to you, as someone who is only a little ways ahead, is to not push the "issues." I got all excited when my hubby recommited and pushed things too hard, too fast. Do not do this as it will "spook the herd"
Certainly there are things that need to be said, and they will be, but try not to force anything. Keep it light and happy as a "reward" for him choosing you and your marriage. The issues will work themselves out over time.
Even now my hubby does not talk about why we separated too much. A little here and there. Do not have the expectation of a massive heart to heart. Maybe down the line look into MC or joint sessions with Jody like you mentioned before. Then you can hash some of it out and make plans to keep things moving in the right direction.
Just never let go of GAL and PMA and you will be happy and mentally healthy!
