Default Help with a 2001 cherokee sport OBD-ll codes

I have a 2001 cherokee sport. The check engine light came on and i had the codes ran. And these are the codes i got back P0118 engine coolant temp ckt high input, P0303 cylinder 3 misfire, P0455 evap system large leak, and P0432 main catalyst efficiency below threshold bank 2. Can anyone help me figure these codes out and possibly tell me how to fix the problems. Thanks

I had the "evap system large leak" code on my '01 and it was just the gas cap. Evidently the seal in it went bad, which caused the emission leak.
