The cat & evac system will not get ready, for it to pass inspection. Is this the cause of a bad 02 sensor?

Step 3 is for the evap monitor and step 4 is for the cat monitor the evap monitor is hard to set sometimes the cat monitor is a lot easier to set. You have to do those steps many times sometimes depending on where you live sometimes they will let you pass smog with one monitor unset.
