I suggest you post the problems in which you are facing difficulty rather learning all the formulas.
Hardly there are any formulas to be listed in set theory.
Even if you learn all the formulas, its the application that's more important in GMAT.
So i feel it would be best for you to learn the approaches of solving different problems.
PS: purely personal opinion.
