The outer handles on these cars can be a bit of a pain to change out. The access is extremely tight and can be impossible without the proper tools... you will want to have 1/4 drive ratchet/sockets and preferably low profile ones at that.
If you do not have access to small enough tools, you would need to remove the window glass to get more room, which is no fun in itself.
To remove the outer door handle there are two 10mm bolts holding it on. The first is not too bad, as it is accessed through the back edge of the door. There will be a plug covering the access hole and the bolt will go in from the rear horizontally.
The second bolt is the more difficult one. It is accessed from inside the door, just behind the bottom edge of the glass with the window up. The bolt is just rear ward of the door lock cylinder and key lock switch.
You want to use a pick or similar to gently pull the lock cylinder switch off the back of the cylinder... these get very brittle with age, so be gentle; they will break easily.
Then remove the 10mm bolt from just behind the lock cylinder.
The next step is open to choice... you are supposed to release the plastic clips holding the door handle lever and lock cylinder lever to the appropriate actuator rods, and you can then tip the door handle out from the bottom and carefully navigate it out/down ward to remove it.
Personally I prefer to leave the lock cylinder actuator rod attached since it can be difficult to access, then proceed with removing the handle... as the handle comes out of the door you will have more access room to remove the rod from the lock cylinder, or if you are really tricky you can release the retainer from the lock cylinder and leave it hanging in the door.
That is just how I do it... you can fight with the 10mm bolt around the cylinder switch, etc, as recommended by the book, that way just seems easier to me. I am attaching a picture showing the location of the bolts and cylinder switch, etc, to help visualize it while it is still in the vehicle. It is not the best picture, but it should help some.
