[DC] Does Batman know Torquasm Rao and Torquasm Vo? And how much do those martial arts actually help Superman given that ancient Kryptonians couldn't fly and he can?

Batman certainly knows every technique he's ever seen Supes use to some extent, and more certainly he has video of Supes fighting, even people in his weight class, and he has used that video to recreate moves to see what he should add to his arsenal of moves, as well as the arsenals of his Robins.  

Supes can fly, but he very rarely just nukes from orbit.  There are plenty of opponents who are too powerful for range attacks and flying into opponents causes a lot of collateral damage, so on occasion, with the strong enough opponent and in the right circumstances, he is going to stand his ground and pound away in a way that might almost look like a regular fight at high speed, not to mention he takes advantage of various holds and joint locks.  In those situations he'll employ his martial arts.
