The only thing on your list that made me laugh was the BoatUS membership.
I recommend you check the engine oil and coolant before starting it up, same for transmission oil. As for fuel, that's easy to come by. What you need are spare fuel filters.
My own boats have never been inspected as thoroughly as the list accumulated on this thread. Well, not all at once anyway.
