For adjustment you would park close to a wall on level ground with the headlights on. Mark the centerlines of both high and low beams with some tape, where the beams hit the wall, back away from the wall to a distance of about 20 feet. Adjust the low beams to hit about 2in. below and the the right of your marked centerlines. As far as the screw direction i forgot what it is (sorry) but while you have it close to the wall adjust the screw and see which direction is which.
