Do you need to replace expansion valve when replacing compressor?
I strongly recommend you change the expansion valve. If the clutch failed there is no reason to replace the expansion valve. If it was the bearing, then you may or may not need to replace the expansion valve, depending on whether or not metal shavings were introduced into the refrigerant system.
What else should be replaced when replacing AC compressor?
For the compressor that is seized, you will at the very least need to replace the compressor assembly and clutch, receiver drier, expansion valve, and flush out the system.

Do you have to replace receiver drier?
The receiver/drier should be replaced any time the system is opened for service, and most compressor warranties require it. Additionally, the filter inside the receiver/drier could be restricted by debris that may have been inside the system. This could diminish refrigerant and oil flow.
What are the symptoms of a bad AC dryer?

When should I replace my AC receiver drier?
The receiver dryer must be regularly replaced. It is recommended that the receiver dryer is replaced every second year or whenever the circuit has been opened. Always install a new receiver dryer any time the compressor is replaced and always when a serious leakage has been noticed and repaired.
What happens when a receiver drier fails?
As we mentioned earlier, the receiver drier removes moisture from the A/C system to avoid clogging, build up and corrosion. A failed component could lead to circuit clogs, abnormal system pressures, lack of performance and of course other damage or failure to other parts of your car’s cooling system.
How often should a receiver drier be replaced?
every 2 years
All filter driers should be replaced every 2 years or by manufacturer’s recommendation. The Receiver Drier’s function in an automotive a/c system is to filter foreign material, remove moisture from refrigerant and to act as a reservoir to supply liquid refrigerant to the TX valve.
Do you need to replace the expansion valve on a drier?
