Maintenance Req Light // O2 Sensor, Catalyst Monitoring, Evaporative System Warnings

Those results does not make any sense. Get a hybrid compatible code reader to retried actual codes. Except if you have some quick cash to throw at parts.

The Gen 2 maintenance warning light serves one purpose only. To let you know an oil change is due.
At ~4500 miles, it will blink a few times when you start the car.
At ~5000 miles, it turns solid.
That's all. Nothing else. If it's on now, all that means is you had the oil changed early. Just go ahead and reset the warning light so it works for next time.

There's a ton of videos on how to reset it. Basically you make sure your odometer is on the odometer function (not trip meter), turn the car off, hold the trip reset button while starting the car back up again. I may be off a bit, so it would be best to review a youtube video or something similar.

Your other codes may be invalid if your reader is not Prius friendly.
