RE: o2 sensor
Sensor 2 is the post catalytic sensor. It only serves the purpose of telling the ECU that the catalytic converter is working OK. It will not affect mileage, performance or emissions. If you don't have emission inspections in your state, and you don't mind staring at the CEL, and you check your car every month for new codes, you can leave it as is.
The oxygen sensors are often frozen in place and require a lot of liquid wrench and time before they will allow you to get them out.
