To add in my two cents on the cost of housing and such.
Case -- rents are gonna run you around $500-600. Efficiencies will be higher (Watch out for some landlords, there are some in the area who take advantage of the UGs who are renting for the first time).
Pitt -- rents would be a little higher. BUT since Pitt allows student to do off-campus housing earlier, there's more competition. Some of my friends at Pitt had to show a statement to their landlord that they do have x income amount, or x amount saved, and can in fact pay the rent on time.
OSU -- similarly competitive, but the prices have a wider range. My one friend did have to get a credit check at some places which costs and additional $40. *shrugs* but that's the only time I've heard of that going on in Columbus
I don't know about the other places you are applying. Point being is that for moving there's a lot to consider. I had a friend move from the bluegrass area of Ohio to OSU and the cost was a bit higher than she was used to. She worked as a waitress for a few months and with just the move, finding a place, etc. She completely drained her savings (and the emergency-save-for-a-rainy-day-fund of $2200 from her job. I don't know why, but just keep in mind that sometimes crap happens when you move. XD Have you asked those acquaintances you know in the area whether they would be available to help you or are you assuming? I ask because when school time comes, many acquaintances are usually too busy to be able to help and flake on you.
Social wise -- my friends at OSU were essentially forced to be socialable, but alcohol is usually involved. Also hope you like talking about football! (Jk -- I have some very home-body friends at OSU, and they are fine without forcibly talking about football) I have MSW friends at OSU, Case, and Pitt and they are usually somewhat tight knit since they share a lot of the same views, but of course, your mileage may vary.
In addition to sites like idealist, I would recommend opportunityknocks Also, maybe you can go to your local community service fair. I'm sure there is one in Univ of Akron. Contact someone at your alma mater who was in charge of community service and they can give you a lot of advice on alternative post graduation. Americorp and Peace Corp are extremely competitive, but you would never know if you can even get it if you don't apply! Peace Corp though will require a LOT of independence. You will likely be in a foreign country you've never been to before and have just learned the language, and may even have limited communication with your family. My friends in the peace corp have to walk a good amount of miles before they can reach the village with a working satellite phone (He was in Francophone Africa though).
