Check Engine codes, any ideas?

I have a 2008 unlimited rubicon and I recently received a check engine light. With the stupid new Ontario drive clean I need to have these clear in the next couple of weeks.

P0430 - Catalyst system efficiency below threshold (Bank 2)
P0058 - HO2S Heater control circuit high (Bank 2 Sensor 2)
P3438 - Cylinder 5 exhaust valve control performance

Could it just be a bad O2 sensor? The P3438 is the concerning one... I'll probably hust take it into the dealer next week but I was hoping someone here could help!

Thanks for reading.
