Basically you need a new oxygen sensor, The fuel trim code is from the computer trying to adjust the fuel/Air mixture to compensate for the bad signal from the sensor. Just change the one closer to the engine, the one behind the Catalytic converter will thow a different code when it fails.
For codes p1188 and p1189 dont change any parts until you check for vacuum leaks, check the air hose after the air flow meter 80% chance
