1/2 inch drive-21MM six-point socket, long style and a 1/2 inch longer handled ratchet. if you can't find a long 21mm socket, just get a 6inch 1/2 inch drive extension.
I'd recommend a torque wrench to assure you tighten the lugs to 100ft/lbs, but most wont want to spend that much or dont think its necessary to torque the lug nuts.
to lift the car you need a jack and a pair of jackstands. if you have never lifted any car up before, I suggest you have someone there with you that has.
