Hi there. Unfortunately, without completing a physical inspection, tell you exactly what parts you need to resolve these codes is simply not practical. I would highly recommend reading these two articles highlighted in blue; P0420 Article & P0330 Article as they will tell you what causes these codes and what possible components are the cause. You can also set up a check engine light inspection so one of our professional mobile mechanics can come to your location and inspect the car, pinpoint the source and provide you with a repair estimate.
