The cans of 134A have this oil in it already.

If you disconnected the A/C lines in the process of replacing compressor, a complete vacuum and recharge is in order. Having lines disconnected introduces moisture in the system and cause damage.

I know some brands of 134a producers do put oil in with there refridgerant but if it enough to service a new compressor? I've found that most cans of refridgerant contains about 2oz of oil.

The following is from my AllData I have for my '01 Stratus. It's probably the same.

Refrigerant Oil

Total System 150 ml (5 oz.)

Condenser 30 ml (1 oz.)

Evaporator 59 ml (2 oz.)

Receiver-Drier 30 ml (1 oz.)

Refrigerant Lines 44 ml (1.5 oz.)

Compressor See Note

Note:
When replacing the A/C compressor, drain and measure the amount of oil from the old compressor. Add the equivalent amount of fresh oil to the new compressor.

i replaced the compressor becuse the clutch on it went out, the compressor itself worked fine before the clutch gave way. No, i didnt replace anything but the compressor.

would add atleast 2 ounces to the compressor you can buy freon with oil in it already but the oil should really be added directly to the compressor and turned over several times by hand before even installing.
what exactly was wrong with the clutch was it making noise and slipping and discolored from being hot if so you will likely be doing the job again in the near future might want to flush and change out the drier the second time around.
