Gas tank issue is probably a blocked or kinked overflow hose or main fill hose. You'll need to get under the car and check that out. They're usually secured to the fill inlet and the tank with hose clamps. Loosen those with a plain screwdriver, grasp the hose ends, and twist and pull. Do this with a relatively empty tank.
You can check to see if there is a shorted wire in the dome light assembly. Most likely it's a switch, though. They are located in the door pillars behind the plastic trim panel. You'll need to remove the lower sill plate on the bottom of the door frame and then the plastic trim panels. First 4 images.
Does the light for the cruise control come on? Check power to the cruise control module and switch. See last image. The 2 images before the one for the cruise control module are screenshots of the schematic for the cruise control system.
