Well, what type of judge do you wanna be? If traffic judge is your highest priority then I wouldn't sweat it too much, won't really matter where you go. States vary on how their judges are installed, either appointed or elected, but odds are if you want to be a state judge you'd want to go to a school in that state or one that's respected in that state. If you want to be a federal judge, good luck, it's a tough road. It's almost required that you go to a T14 school; if you want to be a federal judge as a rule just go to the best place you can get into. Most have careers in government or academia first, not many spend all their time in biglaw but many do have intermittent stints in private practice (John Roberts spent time at Hogan and Hartson). And almost all of them clerk.
Hope that helps. I wouldn't mind being a judge some day either, but I've got time to make the decision over whether it's my career path.
