Scott,
Condolences about your father.
I have the same codes for catalysts on my car, and can echo the previous poster's recommendation on replacing the pre-cat 02 sensors. Amazon has the best price and even has a little app built in to give you the specific Bosch units you need. With a lift it would be incredibly straightforward.
There is another active thread about replacement cats right now, some folks have used Magnaflows if you end up needing to replace them. Much cheaper.
