I have the following codes
P1484 (appearing three times) CATALYTIC CONVERTER OVERHEAT DETECTION
P200E P200E Catalyst System Over Temperature Bank 1
P2032 Exhaust Gas Temperature EGT Sensor Circuit Low Bank 1 Sensor 2


What is going on, and how quickly do I have to fix it?

Not being able to connect the scan tool and look my self here is my deduction. You want to confirm before just going and getting parts. But low bank one sensor 2 would be post CAT O2 probably bad. So now it is not reading it and is dumping more fuel (rich) Which in turn makes the EGT and CAT temp high because more fuel means more fire (usually) Just my poke at a pig so to speak.

I had cleared the codes, but the P1484 is permanent. I had an appointment at the dealership but without it currently showing the symptoms, I cancelled it. Now I have a 2,000 mile trip next week.
