Please keep the court date as getting a date on the docket is time consuming and you don't want to piss off the judge at this critical juncture.
As for meeting with H, I'd suggest that you bring with you a blank notebook so you can jot down notes on what you agreed on and have H review it on site that you BOTH agree on. H is confused and not good with remembering things. You then can use it to fire off an email to your lawyer so they can draw up the agreement.
I suspect that H will disagree with you and may get angry if you are not so accommodating on his 'wishes'. Be prepared for this. You can say, "H, it appears that there's a difference of opinion on certain elements. It is best to let the court system step in to work out these differences."
