I'm 100% with FM on this. You've got to let it go regarding your W's parenting skills. Unless she is endangering the child's life, mum is the word. As best you can ignore it and be like a duck (let it roll off your back). It just causes you stress and it forces tension between you, W and D6.
I have two girls and I don't always agree with what my W lets them do or how she parents them, but I know that she is their mother and she would never want any harm to come with them. So I just zip it and keep my opinions to my self. I'm sure she doesn't always like how I parent them either, but she keeps that to herself as well.
Good start to your list, but you're missing a couple of items.
