Doubt I'll have to do anything, it should pass emissions with no problem since I replaced both upstream O2 sensors, it's got new plugs/wires, I cleaned the throttle body/intake/combustion chambers, and there is still no P0430 code.
I've been driving it in a way that should ensure the catalyst monitor runs more often.
Here is the post from Big Jim that makes me think what I did may have fixed the cat. Let me quote the relevant portion:

With all that said, I have had that code set on my car from time to time and the cat seems to have restored itself. I have not had it on for at least a year. I have scanned the oxygen sensors and the cat monitor oxygen sensors and they are switching as expected, fast in front and very slow in rear. The cat has not been replaced. It may help that I clean the throttle body, intake manifold, combustion chambers, and injectors often and keep the ignition system and air filter is exception condition.
