Codes for 2003 Chevy Monte Carlo

Question

We have an 03 montecarlo 3.4L and we are getting these 5 codes: P0102, P1189, P0327, P0463, and P1811. We are changing the radiator cap, temp sensor, and thermostat with dealer parts. We think that may get rid of a code or two, but we don't know what else to do. Help?!
