I'm buried at work at the moment, but I don't trust your husband. The words he's using, and -- especially his TIMING -- seem very self-serving to me.
Tell him this: "I don't know. I will need some time to think about this. I'm not going to tell you what you need to do, however -- this is YOUR mess; YOU need to clean it up."
You're looking for COMMITMENT here, not COMPLIANCE. If you give him some "list" at this point (there will be a time for this soon, but not now), you're just going to get COMPLIANCE.
I'd test him, stall, and see if he can keep this up for any meaningful (2 weeks?) length of time without getting nasty with you again. Then you'll have your answer.
I'll try to check on you later with more thoughts -- gotta run.
