Do I download the source, build it and replace the files in my website project?
I wouldn't say there is a how-to guide for any specific module use case - only for technologies/patterns.
As for building a module for features that already exist in some form, your idea of beginning with existing source code is spot on. This is discussed in DNNDocs a bit. I wouldn't suggest doing this from within DNN's source code package/repo itself though.
Instead, I would suggest starting with an existing module template/pattern and then applying the existing source code to your new module, as required.
