Suboxone now what else?

My husband is going on suboxone for the treatment of heroin addiction. I was wondering what else him or we should do to help with the recovery and to keep him from relapsing. He really wants any help he can get. The addiction has really taken a toll on our marriage and family. So do you think he needs to go to aa alone AND with me or maybe a marriage counselor? There is a pastor that is also a certified counselor that is willing to help us. What do you think should we do all 3? Or should he just go alone? Sorry if I'm rambling I just really want to get the best help for him and our marriage as possible.
