Bank 2 is passenger side. O2 sensor 1 is threaded into the exhaust system between engine and catalytic converter.
The O2 sensors are located between the exhaust manifolds and the cat converter. They screw in to the head pipes. Those are also called upstream O2 sensors and in some vehicles they are also called air/fuel sensors. There are also downstream O2 sensors that are located after the catalytic converter.

what is included in the z71 package
I'd start with a tune-up; computer diagnostics, plugs, wires, rotor, cap, oxygen sensor, and don't forget the air filter. Check the catalytic converter to make sure there is no back-pressure problems. From there, you'll need to get some professional help.
