Your list is quite inclusive and I would say most of them are applicable to coastal cruising too. I would also say that nobody knows everything and so having good reference material aboard is a key component.
Though I have yet to cross an ocean, having done just a few 300-500nm offshore trips, I have read from circumnavigators their biggest concern is close to shore.
