There shouldn't be two sensors. There should be an EGR tube bung and one sensor bung. If there are two sensor bungs, plug the second.
You need to use some kind of O2 sim on the sensor that was after the precat (probably on the midpipe not too far before the cat). Look around, there are a couple methods of faking the signal, or you can just extend the wiring on it and put a bung in your catback to put it behind the cat.
