As a result of super storm Sandy, & Nor'easter, the 5ft tall Leucothoe are leaned over or practically on the ground. Should I prune them back or leave them alone

Without seeing the conditions around the plants, it is difficult to say for sure what would be best.
If the roots are intact and have not been damaged by the salt or cold, I would try to reposition them upright, assuming I could dig out the soil to make room to reposition the roots. You may need to stake them temporarily until the roots can provide anchoring.
You may want to contact professionals locally who can better evaluate the situation.
