Hi KJ88,
The speedometer jumping around could be due to a faulty speed sensor located on the trans axle differential housing below the thermostat housing. It could also be related to the lights flickering and I would suggest rectifying the the lights flickering first.
Possible causes are:
1. Bad body ground. check all grounds at front fender inner side behind headlights.
2. Alternator. Check the charging rate, ensure crankshaft pulley harmonic balancer is not faulty ( if equipped) before testing charging rate.
