In what order should i do everything?

So it sounds like your new headers have the one pipe that runs under the cross link?

I went with Doug;s headers specifically to avoid that.....figured it would improve ground clearance issues (I already have a deep sump oil and tranny pan combo)....plus ease of install/removal if needed.

yes i believe my headers go under the cross link. not 100% sure. so i have to read the instruction sheet for them again. but i remember i have to take apart something with the front suspension/steering..
