Green screw terminal: The green screw is the ground terminal. Two ground wires will be found in both switch boxes, one from the 14/2 cable and one from the 14/3 cable.
Do all outlets have a neutral wire?
Houses built before that may or may not have a neutral wiring. If there is an outlet (wall receptacle) near the switch, most likely that switch has a neutral. Switches that are ganged together have a much higher likelihood of having neutrals, no matter what year.
