Yeah - I wouldn't float a settlement agreement until you've gotten some legal advice. Make sure you're not giving him more than he's entitled to.
And frankly - it concerns me that there are so many items that you're willing to give him time after the divorce to take care of. I'm not divorced but I think many people here have had problems with items that were left for after the divorce. Try to get everything settled BEFORE the divorce is final - you have no leverage after.
