Are you trying to restore this to full OEM condition or are you adding all of this stuff simply to pass emissions?
If the latter, I would first take it to one of the service centers that can tune your rig to pass and just have them do a basic test on it to see if it passes the emissions part. If it can be tuned to pass, I would go ahead and take it in for a test. The worse that can happen is they fail it on visual inspection and you can move ahead with getting your list of parts.
