The speedometer issue sounds like a cracked solder joint/poor connection on/at the instrument cluster.

You will need to remove the cluster and reflow all of the solder joints on the clusters printed circuit board,
If you want/need more info Please feel free to ask.
The odometer being inop is also a very common problem with an easy fix, everybody that has owned one of these cars for any length of time has had to repair an inoperative odometer.
The speedometer is electric and it drives the odometer mechanically through a set of gears, the gears break.
You can buy replacement gears here...
There is also a video leading you step by step through the gear replacement.
