Default CEL on P0432 and more

First with the basics
Ive got a 1999 S80 2.9 N/A. It comes up with a PO432 which is three way cat bank 2 efficency below threshold, and a Evaprative SYstem Gross leak no fliow code as well.

Then once in a while it wiill say fuel cap open loose. But it isnt and I have replaced the cap. I have heard several people with that code, who have dropped the tanks and found cracked vac lines. Which fixed the problem.

My first question is does anyone think the evap code and the cat efficency code are related?

My next question is what are the chances that replaciing the 02 on that bank will help? I have checked for intake and exhaust leaks already.

Please help
