I just took a capacitor off of a box that has been sitting in my basement for about a year or so. I'm not quite sure if i need to charge it, or discharge it, or how to do either of those.

If it sat for a year its de-energized. Put a screw driver across both terminals to be sure. If it dont spark, its empty. Charging it involves a bulb.
