I'd actually differ with that advice. Considering that you're well past the 100K recommended replacement interval, I'd say yes, change them, at least the front pair. Cheapest option is the Bosch "universal" type (look up the correct part number on their website, then search it on Amazon or other online vendors) where you re-use your harness connector and splice it to the wires on the "universal" sensor. But if you're paying for the labor to have it done, buy direct-fit.
Assuming your main cats are shot, you should probably pay a bit extra and have them remove the rear cats and dump them out. The fronts can fail by disintegrating, and the pieces end up blocking the rear cat.
