What is your question?
So I have several codes that pop up: P0340 P0303 p0344 p0430 P0420 and I have replaced the Camshaft sensor A, a new alternator was replaced. The truck runs fine then it starts to shake and it has a rough idle. So researching these codes, am I looking at replacing the Catalytic Converter both sides, or the Camshafts? How hard would it be to change myself?

You'll need to test the camshaft position sensor, and the wiring harness going to it. The P030X codes are all misfires, the P034X codes are indicative of a fault with the camshaft position sensor, or the camshaft sensor circuit. The P04XX codes are probably a result of the misfires you're getting while the PCM doesn't register the camshaft sensor.
