Well, let's start with location. Which state/town/city do you want to go to school in? Think about commute in addition to everything else, unless you want to move to be closer to your school. Even if you live in a dorm, since you have children, you will most likely find yourself working, so you'll need to consider employment opportunities in the area, and not just at the school.
So let's start there.
