Check the voltage regulation. A wandering tach needle is often a sign of too high voltage from the charging system. That will kill things quickly. If you drive at night and see your headlights varying in brightness, that's a dead giveaway. You can check it with a voltmeter. Also, check the water level in the battery. WWear eye protection.
The gauge problem could be in the sending unit or the gauge. Check the sending unit first. A search here will turn up a how-to post.
