to me, csu sounds like a better option than the other two. i also read that cleveland has the largest legal market between chicago and new york...for whatever that is worth.
i would look into the on-campus pricing. csu recently renovated an older administration building (fenn tower) into living space. it looks amazing from the photos. also, csu just either built or renovated its rec center. http://www.csuohio.edu/oncampus/09-13-06/page3.html
i just read about the in-state tuition requirements. you either have to work and go to school, or as you said, have a spouse working in cleveland.
regarding transportation, i would not rely on the public transit system. i thought the trolley was just for tours of cleveland. maybe it does serve as transportation. it's just a fancy looking bus. of course there are buses, but again, i would not want to rely on waiting if i did not have to. however, if you lived on campus, you probably would not need a car. the law school is in the middle of the campus.
