Welcome to the forum.
1) If you connect somehing in parallel with the motor and we assume that the supply impedance is low, you will not affect the efficiency of the motor. The same voltage will appear across the motor terminals and the same current will flow into the motor.
2) The current flowing from the supply is a combination of inductive magnetising current and resistive work current. Connecting a capacitor across the motor will reduce the inductive cruuent drawn from the supply but will not alter the current into the motor.
Have a look at our power factor correction page for more information.
