RE: drain plug
how big is your wratchet? May want to buy a breaker bar or something with more leverage. You could try putting a pipe on the end of the handle to make it easier. Just be careful not to strip the drain plug.

You may be able to apply more torque with a box-end wrench than with a socket. I have had pretty good luck loosening stuck bolts by tapping on the end of a box-end wrench with a rubber mallet.
