1997 Saturn SL2 Speedometer Issues

I have a 97 SL2. I bought it from an online auction. It had some front end damage. I had to replace the engine bracket and frame. I currently have a service light with a wrench, and a service engine soon light. My speedometer is intermittent. It will kick up to the correct speed when I hit rough road or tap on the trip reset button. The odometer works, but not the speedometer. Today I was driving and the speedometer went completely dead. Then I had problems with the car rpms going to zero and the car stalling when I tried to shift gears. As a side note, I also do not have background lights to any of the instrument panels including radio. It makes it kind of difficult to drive in the dark. But the warning indicators work.
