Consequently, should I use plastic or metal electrical boxes?
Plastic boxes don't use metal cable clamps and do not provide the required grounding path. Metal electrical boxes are primarily used with metal-sheathed or "BX" wiring. However, they can also be used with Romex or NM wiring if desired. Most new residential electrical systems use Romex and plastic boxes.
How do you get a broken screw out of the electrical box?
Grab the back of the screws with a pair of 9's (linesmans pliers) and rotate them through (turn clockwise from the front). If that doesn't work, you can drill it out carefully with a 5/32" bit and re-tap the threads with a tapping tool.
