Tirerack is helpful. If you call them up they can help you pick out a set specifically for your car.
I personally have Blizzaks on 16 inch steel wheels. You're in NJ, I would say that studs are quite overkill. You don't want to drive studded tires on dry pavement, and you don't want to use the stock summer tires when it is below 40 degrees out. So you want performance snow tires that you can drive on safely when there is no snow but it is cold out.
