I would say that the first two issues could well be related to the ccm, the O/S/R door is more than likely the micro switches in the door lock can be re-soldered but i tend just to buy a new lock (saves hassle) this can also affect the interior lights.
the dash is another issue it "could" be related to the ccm but more than likely has an internal fault, personally i would sort out the rest of the problems dry the ccm out fully and make sure all the wiring connectors are clean and free from corrosion, also check the connecting plug at the bottom of the passenger side A pillar as these are known for corrosion, if that still doesn't sort out the dash then have to look at other options
