Answer to Question 1

High/low pressure control, condenser fan, receiver tank, suction to liquid line heat exchanger, filter drier, evaporator fan, thermostat, and suction line accumulator.

Answer to Question 2

Run capacitors have some sort of a mark, usually a red dot, to indicate the terminal that should be connected to the run terminal. With this arrangement, an internal short circuit to the capacitor case will blow the system fuses without passing the current through the motor start winding.
