Bank 1 sensor 2 is the rear sensor after the cat. Try changing that sensor and see if the problem goes away. However, looking at the codes I have to wonder if there'* a problem with cylinder 3 and a weak fire causing raw fuel to enter the exhaust system and over loading the cat, and that is causing the problems with O2 sensor 2

You will really need to get a MAF, you need to run on real data, not hard coded tables. Without real time data the AFR can't be set right. If your running rich it will over load the O2 sensors and kill the cat.

I have found a few times now a leaking EGR tube will cause a idle like this. The only way to really tell if it'* bad is to remove it and hold it up to the light.
