Can someone confirm that "P0157 O2 Sensor Circuit Low Voltage (Bank 2 Sensor 2)" is the passenger side sensor after the cat? I crawled underneath and inspected it, and I didn't see any frayed wires. The plug is tucked up where I can barely see it, but appears to be connected properly. Anything else I should be looking for?

And if I need to replace it.....Is Napa's part# BSH 15511 the correct sensor?

That is correct.
Passenger side downstream sensor.
It should be very easy to see and to get to.
Not sure about if thats the correct part, I'm too tired to go looking right now. lol
Just go to NAPA and tell them what sensor you need. They may even help you install it if they're nice.

And if you don't feel like doing it yourself the just go to the dealership.
I had them change my drivers side upstream sensor(the one thats really had to get to) for $135 even.
And they even washed and vacuumed my jeep.
