From what I see I would find a new shop to go to. Your truck only has 2 cats, NOT 3. Bad vibration from the torque converter? How did he come to that conclusion? I hate seeing receipts like these as most of the time it means they didn't really check anything. The P0420 and P0430 both being in there concerns me the most. I would check the fuel pressure on it to make sure it is up to par. If it was one or the other I could see a bad cat, but both at the same time normally means a fuel delivery problem or an injector issue. How does it start cold? How does it start hot? Do you have problems restarting it hot after it sits for about 10 minutes? To remove the cats there are a few different ways of doing it, but all of them are pretty illegal and the EPA is out for blood here lately over emissions equipment tampering. PM me for ways to disable them for "testing" purposes if you want. Also the P0440 could be the cause of your P0420 and P0430 codes. If the evap purge solonoid is stuck on, then it can cause a rich fuel condition causing it to surge or buck as well as throw cat converter efficiency codes.
