If you have to ask then maybe you should look for a youtube video to see what you are getting into. Even if it isn't the same vehicle, just so you have a better idea. The last time I changed a compressor I replaced the dryer as JoeH suggested, but also the refrigerant control as the instructions I got for the job. The job went well, with a bit of labor, but then I am a HVAC/R repair technician with the right tools, and many years working on residential HVAC/R systems.
As ScottG says, "There are no shortcuts" and you could end up with more problems down the road.
