Shielding helps keep your bass quiet and free of hum caused by fluorescent lights and other things. You line the control and pickup cavities with copper foil, solder the the ground wire from your bridge and jack to it (or, preferably to a crimp ring around a screw driven into the control cavity), and then connect the various foiled cavities to ground by soldering wires from them to the control cavity. It's pretty simple - it just takes time.
