Welcome. If you don't already have one, you will need a Honda service manual. You will also need an indoor (or at least covered) place to work, to keep tools, and store removed parts. I recommend tagging the bigger parts, and putting small parts in ziplock bags and writing a description of what they are, and where they go. That might not seem necessary, but similar parts all start to look the same after a while. I would also take notes and even pictures. And do it slowly. I have removed parts before that could go back together either way, but only one way is correct, and forgotten which way they went. The Rebel is about as simple as a motorcycle can get, but it still has several thousand parts.
