I would start here.
The codes seem to be related, but if the problems persist, I research these topics....
Purge Volume Control Valve
EVAP system leaks
Also, in case you dont know (I just had to tell my coworker about this for his codes, and he was doing this annnnd it caused damage), do not overfill your gas tank. Once the pump stops, do not continue to fill in small amounts/bursts.
Hopefully its a piece of cake, happy repairs.
