the codes thet you are reading are from the instrument cluster only, and most of them are not trouble codes, but just seriel # and build date codes and stuff like that.
the light on the dash are supposed to come on when you start the truck, it is the computer testing them, it's called a prove out. also yes the mileage is stored on the pcm, and cannot be deleted by disconnection the battery or any othe way.
