regarding 3) I'd say it depends on how well the car has been taken care of before.
Suspension will probably need attention (unless it has been done already). You can drive with worn supension parts (ie all the rubber bushings), but it is no fun.
How about water pump, radiator, alternator? Have these items been replaced? Does the AC work fine? Is the blower motor noisy? Does the cruise control work? I guess steering and transmission are fine, if the car was treated well before.
