You need to consult with a lawyer who handles estate and probate matters. The big problem is that you have no paperwork showing a transfer of your father's interest in the home to your mother. Even if you record the new quitclaim deeds, a title search for the property will show that you do not have 100% title when you try to sell, and the sale will be held up as a result. Without reviewing the original deed to your parents, it is not possible to tell you what needs to happen to transfer your father's interest in the property to your mother's estate, and then transfer the property to you. An experienced probate attorney will be able to handle that matter for you. Best of luck to you.
