Hello! A bad catalytic converter can make a car overheat by causing a backup of pressure in the cylinder head. If the Elantra is overheating, I would have her towed to a reputable mechanic and have them replace the Catalytic converter, and do a full fluid flush/change (engine oil, and radiator/cooling system). I hope this helps, and best of luck!

I also just looked at your photo. All that brown fluid, is your engine oil and your antifreeze (or coolant) mixed together. This is KEY INDICATOR of a blown head gasket. Do not drive the car as doing so will severely damage the engine if it hasn't already. I would have the car towed to the nearest reputable mechanic as soon as possible. Again, I would not recommend driving the vehicle. It could irreparably damage the engine.

Usually no, the main cause of radiator failures is poor maintenance followed by an engine failure of some type ie headgaskets, thermostat, etc. When a catalyst is going bad you will notice a loss of power and an increase of fuel usage and a check engine light. It is a Hyundai so if it is just a catalyst and a radiator and they are available aftermarket, it shouldn't be too hard on the pocket book, but after all it is a 15 year old car, so do the math and figure how you want to proceed.
