the po303 and p0305 codes are indicating a cylinder 3 & 5 MISFIRE respectively. the other codes are for o2 sensor and fuel trim. the misfire codes should be fixed first and then worry about the others if they still exist. if the vehicle has direct ignition or coil on plug, this is a good place to start, the ignition coils for those cylinders. a scanner with a misfire monitor would really help to narrow done the problem and as always a tune-up never hurts if it hasn't been done for some time or plugs, air filter, etc, show signs of deterioration. the misfire codes if left untreated will release raw hydrocarbon emissions into the environment not to mention the damage it could cause to your catalytic converter due to overheating. also your gas mileage will suffer. hope this will help yoy
