No way to really determine the whine without being there, but check the rad fan/clutch for locking up, common issue. On the speedo the usual culprit is the speedo head itself or the stepper motro that drives the speedo, the cluster must come out to fix this, may not be a dyer type repair. The starting issue could be the ign switch, the starter relay or the starter itself, circuit checks must be made when this occurs, I would suggest a factory manual if you attempt these repairs. The gas gauge could be the gage or the tank unit, again the FSM needed to check this out properly.
