I dynamatted my doors a while back. I recommend using big pieces to cover up the large wholes in the doors then cut smaller pieces to fill the surrounding areas. It is just a matter of preference some like using large pieces and other small strips. Just make sure to test fit before you take the backing off then heat the piece with a hairdryer before you put it on, then go over it with a roller. As for the wires many people just dynamat over them but since I did it myself I took the time and cut all the holes for the wiring clips, that way the mat is more secure to the door panel. For the hatch you just have to take the plasic trim off from the inside and dynamat the entire hatch, I still have to do this. His is a few pics of my doors.
