A while back, I had to do that to replace a broken window regulator assembly.
There are only about 2 or 3 screws to remove, they are located in places that are not immediately obvious.
The bezel around the inside door handle can be carefully pried out, but I seem to recall that you don't really need to renove that piece...it can be left alone.
Carefully pry up the switch panel on the armrest and unplug the connectors, there are a couple of screws hidden under there if I remember correctly. I believe there may be a couple of screws near the bottom of the door panel.
Once the screws are out, simply lift the panel upwards to disengage the plastic hooks of the door panel from the sheet metal of the door.
I'm going by memory here so it is a little fuzzy, but this is the general idea.
There is a YouTube video I saw a while back that shows exactly how to do it - couple of stereo installer guys were putting in new speakers, so the panels do have to come out.
Hope this helps a little!
