Regarding 3 I believe it's matter of doing it sooner rather than later. You can pretend that things don't have a type, but it's a lie. The only thing that languages like JavaScript do differently is to hide the types of variables. This forces the person reading/writing the code to keep track of what is on what variable at all times instead of having a compiler do it for him. I understand people have difficulty with pointers and such, but not types. Without that knowledge you can't go anywhere. From my point of view there is absolutely no advantage in hiding types when you always end up using them. Better to face the fact and teach them early on.
