Industrial slant timing cover leak and other problems.

So just last week I took my motor out of my 64 Valiant to replace the oil pan gasket because of a rear seal oil leak. Did that, but right before I put it back in I noticed timing cover leak that seemed to be coming from where the harmonic balancer slips in.
I also noticed before and fter that the harmonic balancer had a sorta weird wobble to it. Nothing to get me too paranoid, but paranoid nonetheless. Could this cause more trouble down the road? The leak is more like a large area of moisture rather than a dribble and leak.
I also had trouble with keeping my car running and charging after the oil pan gasket replacement. I had warranties on my alternator and ballast resistor but had to buy a new voltage regulator. I turn the ignition and the valiant started up right away but right after that the new ballast resistor fried up! I might have a short somewhere but I don't know where! I checked under the dash and the wiring harness but everything looks beautiful. My alternator can't keep my car on after I disconnect the battery terminal and my ballast resistor gets way too hot. I just wanna drive my car already!
