I just watched Newpower99's video on how to replace the battery. It looks to me like it's pretty straightforward. They provide all the tools you need with the battery. The only difficult part seemed to be removing the double sided tape holding the battery down but it doesn't matter if you screw that up since you throw it away anyway. It's not really needed.
You might want to watch that video and see if there's some help there getting your Fire Phone to work again.
