at that time of night you should be ok, you can take the air train to Jamaica and the LIRR into Penn, from Penn youll have to get to Grand Central and take the metro north. The AirTrain is run by the port authority so it won't strike.

For Williamsburg just grab a yellow cab it wont be hard they have cab stands they come there all the time

As far as your Cabby knowing BK, uh , good luck, I would mapquest it your self so you know where to go. When they go up to the Bronz for me there lost by the 3rd turn unless they been there/live there.

For you the Cab isnt a terrbile idea its a flat rate, should take you about 30-40 minutes from JFK to grand central. I amke that trip 2-3x (in reverse) when I have to fly out.
