Need pointers on replacing O2 sensor - 2000 Isuzu Trooper

Check Engine light on, getting this code:
P0430 = Catalyst downstream, Bank 2

I've reset the Check Engine light but after a week or so it comes back on.

Thought I would replace that O2 sensor.
But, never did this before and looking for pointers before I order part and do the replacement.

Special tools? Is the sensor easy to get access too?
I would guess its in one of the exhaust pipes.

Do have an Exhaust leak - maybe its the leak?

Think I can get the O2 off by spraying PB Blaster on it and using an ordinary 22mm wrench without damaging or cutting the wire?
