I am getting 0300 code and 0303 and 0306. i am thinking that my cat might be clogged or damaged inside. when i was checking exhaust the exhaust tip one side was warm the other was almost cold. i have notice that when i was warming it up in the morning that one side had condensation on the ground and the other didn't. any clues out there?

Chances are your CEL is flashing - If so, the car should not be driven.

P0300 Misfire Damaging to Catallytic Converter

P0303 Misfire, Cylinder 3, Damaging to Catalytic Converter

P0306 Misfire, Cylinder 6, Damaging to Catalytic Converter

Hmm... cylinder 3 and 6 are on different cylinder banks. Have the spark plugs been changed recently?
