Ac oil helps to keep the gaskets in the ac system from drying out. The oil can be added separately or can be bought mixed into Freon from the store. Most importantly the oil lubricates the ac compressor, the only moving part in the ac system.
Off. The only way the engine being on would benefit you in any way is if you had the AC on, to assist with the evacuation (with proper equipment for evacuating an AC system does not require). The refrigerant also carries the oil for the compressor, so you're effectively running that compressor dry of lubricant if you run the AC system while evacuating refrigerant.
The freon has to be removed and the pressure released from the ac system. Then the valve can be removed and replaced. The system will need to have a vacuum pulled and freon put in again.
System pressure will run abnormally high, the AC system will vibrate, and you won't get proper cooling.
A refrigerant (freon) is required for an A/C system to cool. Therefore, no, the A/C should not work is the freon is removed.
The AC system will vibrate, and pressure throughout the system will be extremely high.
