There's only the one bracket you need to remove to get the door off (lower front). Before you pull it off it's a good idea to mark it's position (bolt head washers to bracket). You can circle with a sharpie or perhaps scratch with a scribe, etc. As long as you put it back the way it was before there's no need to align (door will be the same as it was before).
I have replaced that handle before, but it was many, many years ago. If I remember right it was a little frustrating, but not impossible. Handle worked when I finished (I remember that much)
