I don't know... this might be codependent, but my thoughts are:

1. He's currently in recovery
2. He listed some things in the "moral inventory" of things done in the past
3. Whether or not he left his stuff around, it is still an invasion of privacy to read it without permission IMO
4. Nonetheless, it leaves you with stuff to process about his character

It sounds to me like he's trying to deal with stuff doing his Step work. If you can't deal with what might have been in the past, as suki and others have said, you need to decide what you can accept and what you can't--but rehashing the past with him when there's enough to deal with now might put too much stress on recovery and your marriage--can you handle that?

I think if it were me, I would try to process this information on my own, but would be vigilant with my boundaries from now on with regard to his behavior. If you find yourself in a safe place in the future, like in joint counseling, and the stuff is still swimming around in your head, maybe bring it up where you both can neutralize it and decide what to do about it with a trained professional, because if you just do it on your own, I just don't see it having a good ending.
