I have a way too detailed header install procedure on my website. It is for JBA's on a single cat car, but it might have some helpful hints.

Sounds like you are approaching it correctly with the plugs and O2 sensors.

 

when installing the headers all i can say is take your time and go step by step. since there shorties that makes it alot easier. air tools makes it alot easier to.
