Rule of thumb: if it says "Auto", change it to "Manual". Auto means that the camera will adjust itself as conditions change. That's very useful when filming live-action, but winds up being bad news for animators, because we don't want the camera to change its settings based on a hand being shoved in the shot between frames. The other stuff is subjective. We can't tell you if it'll look good or bad without knowing more about the shot you're filming. Honestly though, you should just play around with it and see what works. You'll learn more from that than you would from having us tell you what to do.
