I think not looking at the original X source code is probably a good thing. The protocol is reasonably well specified, and you can further use the XML specification used for XCB. Most of the requests are pretty simple.
For some of the trickier ones it might be worth diving into an X11 implementation, but you can also defer most of the trickier ones other than getting the event handling right (most of the old school drawing API mostly matters if you want to run 30+ year old software that hasn't been updated much since; that said it might be nice to be able to run twm and xeyes - I have a whole separate file in my own X11 server for legacy stuff required to run twm and xeyes and similar ancient software, but not useful for anything else I actually care to run...)
