Unless your vehicle has 200,000 miles on it, there's no way a 2005 vehicle would need a catalytic converter replaced this soon. Your garage is either incompetent or ripping you off. 

The gross leak in the evaporation system code is a fuel vapor problem. It means your gas cap is defective or there is a crack in the fuel filler neck or maybe a bad fuel tank vent hose.The EVAP system collects fuel vapors and delivers them to the intake manifold, where they are burned with the normal air/fuel mixture.

Buy a new gas cap and hope for the best. If that doesn't solve the problem, you will need to go to a good garage that has a clue. You can ignore the problem for a little while if the car runs okay, but you car will eventually run poorer and poorer if you do not replace the damaged part.
