As the survivor of a joint bank account, those funds are yours and do not have to go through probate. You are not obligated to pay the mortgage payments for the house. However, if you do pay them, then you are entitled to be reimbursed by the estate. As a practical matter, you may want to continue paying the mortgage until the transfer of the house is sorted out for the beneficiaries.
If your sister had a "pour over" will that gave everything to her trust, then you may transfer the house to the trust with a Heggstad Petition. Otherwise, you may need a formal probate proceeding.
