Yes, a person can put to much oil in a car. It usually will not hurt a car, but the excess oil can cause smoking if it gets on the motor.
It is best to do it while your vehicle is running so it will circulate through the system. You should add it to the reserve tank, never open the cap on your radiator (if it has one) while the system is hot.
No.

You put engine oil in at the oil fill cap. It is normally located on the valve cover.
