This is good. I would not open it unless necessary. Mine had surface corrosion too, I brushed off the aluminum oxide and put a coat of rustproofing between the case and mounting bracket.
Did you try to re-set the codes? Do they all always come back in the same order as above?
Next I would check the battery, its cables, ground points, grounding cables and the alternator, as you have so many malfunctions that there must be something common to cause that.
For now I would ignore P0420/30 and P0300, they can be dealt with later, but the rest all must have an electric origin, unless all those sensors are simultaneously broken, which is unlikely IMO. If feels like you either have a short or degraded wiring somewhere. A squirrel nest? They chewed on the wiring? Possible.
