Keep it simple. Also, I really like the "leave everything at home but the jig box" thought. As someone else mentioned, once you have a great day of jig fishing, it's hard to put it down.

15-20 lb line or 40 lb braid is what I use most for jig fishing. If I were starting from scratch, I'd stick with black/blue jigs and green pumpkin jigs. Go with an arkie style. 1/4 oz, 3/8 oz and 1/2 oz weights will do the trick 99% of the time.
