82K, first MIL....great.

Trouble code P0425, (Catalyst Temp Sensor, Bank 1, Sensor 1)

Someone please new-school the old-shool guy. Learn me something here.

Is it correct to assume that a catalyst temp sensor is also the heater in the O2 sensor?

Well, when my friend had that code, it was the 02 sensor heater. replaced the 02 sensor and fixed the problem.

O2 sensors are cheap. Easy fix.
