P0420 indicates you have a catalyst efficiency issue; replacement of the Air-Fuel Sensor should take care of that;
The P0441, P0446 and (I assume P0440); you said 446 twice, indicates a faulty or loose fuel cap; it is not sealing properly.
Please feel free to respond to me if you have any further questions.

code p0440 refers to evaporative emission (EVAP) system--malfunction=== causes --hose connections --intake leak--EVAP canister purge valve
code po441 refers to EVAP --incorrect flow detected==causes the same as for po440
code po446 refers to EVAP system vent control --circuit malfunction===causes --wiring---EVAP can purge valve--ECM
generally I would replace the purge valve as it is common to all codes
Code 325 is for a problem with the knock sensor circuit, code 441 is for an incorrect flow with the purge valve and the vent for the gas tank, and code 446 is also for the vent control circuit. I would clear the codes and see how many come back after a test drive. You may need a shop manual to test the circuits.
According to my 2002 Toyota Tundra manual (and it may be different for your car) P0125 is as follows: Insufficient Coolant Temperature for Closed Loop Fuel Control
This would seem unrelated to your original problem.
Both codes are with the EVAP SYSTEM, there are numerous items it could be. A repair shop that does Toyotas or the delaler would be the best to check it out for you. Its not anything that will leave you walking or disable the car.
