I've had to replace both the door handles on my 1g and my 2g and it's sort of similar. Once you have the door panel off and the plastic liner peeled away it's pretty straight foward because you'll be able to see what you need to remove. If I remember right there are two 10mm bolts holding a 1g door handle on and you will also have to remove the linkage for the lock and the handle. Oh and it was easier on the 1g than the 2g to replace
Also the bolt in the 2g article that they mention it hard to get to is really easy to take off on a 1g. There's a hole that you can fit an extension with a socket through to take it right off.
