AC Compressor not working!

Guys,
My ac stopped working. I took my car to the dealer and was told my ac compressor is faulty. i just bought a new denso compressor, a new drier, a new expansion valve, oil and o-rings. i'm planning on taking it to an indie shop to have all those parts replace.

How hard is this job and does the car have to be reprogrammed at the dealer in order for the new compressor to work after replacement? Is it hard to replace the Drier and expansion valve? Thanks guys.
