both O2 sensors are in about the same place, across from each other... just as the pipe bends down.
You can use any number of O2 specific tools.
I recommend NTK (NGK), Denso, Delphi or ACDelco O2 Sensors.

Both are on the top side of the exhaust. Driver side is super easy. I actually just changed mine this sunday. Took about 20mins. The passenger side is a different story. The plug is harder to get to. You can get a tool loaner at autozone to help you get the o2 sensor out
