So, let me see if I have this right. Please chime in and let me know.

First I disconnect the primary from the secondary. Then I undo the nuts on the header bolts. Then I pull the primary away and swap out gaskets.

What am I missing besides going in reverse to finish the job? Will I need new nuts for the header bolts?

You may not be able to move the primary away without removing the EGR tube. IMHO, it's easier to remove the EGR tube from the other side, two (12mm?) bolts. Other than that, you've got it. You won't need new nuts / yokes (fatty washers) uless you break / lose something.

Minor point, but disconnect the O2 sensor's electrical connector and where the connector mounts to the bracket.

1. Correct.
2. No need to replace the header bolts. Make sure you put some anti-seize on the studs.

Then finish the job.

There's also a specific order for loosening and then tightening the primary nuts. Check se-r.net, the diagram is on there.
