It's very reasonable to ask to speak to manager #1, since you haven't technically spoken to them about this particular job, to ask more questions. IMO, it's also not unreasonable to ask about time frame for moving to days. No matter what that time frame is though, it sounds like job #1 makes the most sense. It sounds like it's set up better for a new grad experience. You could always move on after a year or two if you can't move up to days. Nights are really hard, but there are lots of tips on AN about how to make the best of them, and they're not forever (unless you want them to be! some people turn into die hard night shifters).
