That's a tough situation to be in.
I do know that alcoholics often do really, really well while in prison -- simply because they don't have access to their drug of choice. The challenge seems to be making the transition from prison back to society.
I don't have any first-hand experience of having a loved one incarcerated, but it sounds like you're making plans for doing all the right things, taking care of yourself. And beyond that, the only thing I think I would try to do in a situation like that is take a day at a time and not borrow trouble from tomorrow. As you go through your recovery, you'll figure out step by step what you want and where you want to go and who you are -- and that will answer a lot of your questions.
