What are my responsibilities if I surrendered my home, filed bankruptcy 01/2013, and now in foreclosure?

There should be no responsibilities. But instead of just walking away, I urge you to try to negotiate a "cash for keys" deal with the lender. Many banks are willing to pay moving expenses or other cash settlements in exchange for the borrower signing a deed for the property to the bank. This saves the bank the time and expense of foreclosure and eviction.
