And it's at THAT point that I need the pursue the Sep Agreement (cause she drags) and she'll see her "going away present" is a debt, not a cash prize.
Do what Pookie has done successfully in the Newcomer's section whenever his W put pressure on the house sale. He told her, "I need to focus on my own priorities that need attention. The house sale is not a high priority." If W pushes and persists, simply tell her "I am sorry that you feel this way. You are going have to make the contacts yourself." Keep reminding yourself that the onus is on W to do the leg work.
Then sit back and watch.
As for the truck, I would not contact W until you resolve the insurance issue yourself and see if you can take over the lease. I do not see the urgency in this matter at the moment. If possible, I'd wait until after OM starts his school year to gauge where things will move.
