If it was me, I would also perform a complete tune-up based on the mileage, which include spark plugs, all filters (air, cabin, fuel, and PCV). You should also clean the throttle body and use some injector cleaner.
Your O2 sensor is recommended replaced every 100K miles. You have 3 O2 sensors, but the ones that you need to replace are the one on the exhaust manifold. When you go to purchase, tell them the O2 sensor for the upstream/in front of the catalytic converter.
