I think that your list is fine, but question what you mean by "crew". Is crew guests, or is crew out for a night/week of racing? Big difference!
I have a list that I give people that are guests on the boat. Mostly non sailors, but it hopefully relaxes them a little. Points out what COULD happen, and never has, and what counter measures are available, to reassure them about the boat.
Basic things like: Do as much or as little as you want, lines under tension are under lots of tension, don't put anything you value between the boat and the dock, and the boom and the head are the two most dangerous things on the boat. Use them both, don't abuse them!
Serious crew, those that are sailors and operating the boat, we talk about duties and risks. Non serious....I sail, they do what they want as long as I show them what to do.
Jacklines and tethers...have them! When it is blowing, whether alone or with crew, we use them. We practice MOB and plan NEVER to have a MOB!
