I was doing this last Friday.
As said, remove the two (or three) screws around the bottom and edge. Remove the screw in the inside door release. You may need to wiggle the plastic piece to clear a lip of the inside notch and then this plastic piece can be removed. Rotate the bottom of the door card out, so the card is now loose, and then wiggle the top which will lift out vertically. It may catch a bit at the front, so more wiggling required. As you lift the door card away release the window switch connector and the two leads to the speaker.
You will need to remove two plastic panels to get to the inside where all the interesting bits are. When you replace these panels don't forget to seal the edges will silicon, or some such. When replacing the plastic around the door release make sure the lip at the front in located in the notch and don't over tighten the screw, as it's very easy to break this plastic piece, and quite hard to find a replacement.
