the front jack point is fairly obvious, and yes the rear diff will work for the back. jack the car up in the front, put a jack stand on each side under the driver's side door and passenger side door. there is a rail on each side under the doors, there are cutouts in this rail where a jack goes. i believe all modern cars have this. the owner's manual shows you this, id take a pic if it wasn't dark.
also, i've painted wheels and will never do it again. wait til ya need new tires, dismount the old ones, have the wheels sandblasted and powdercoated, get new tires mounted on the freshly powdercoated wheels, never ever worry about them again. or be a cheap ass and keep repainting them every few months or any time you need to go near the lug nuts with a wrench, whenever you encounter any type of non-manicured road, etc...
