decrab in flare on both 737 and a320. Have never seen a 737 come down with wing-low method on approach. If you do this you are a minority.
As for all engine out method, just stick the nose down and pitch for the runway threshold at FULL flap. You won't be at optimal glidespeed so you loose altitude faster.
Unless you picked the shortest runway in town the wheelbrakes will stop you, just don't try to achieve a smooth touchdown.
