engine light
I have no idea how to look and where to look, since this Benz is my first Benz, and my first car.

You can use Bosch. Just use the genuine OE Bosch sensors with heaters made for Benz. The Bosch generics do not work.
There are many Benz online parts stores & you have the P/Ns you are looking for. I'm in South Africa so I'm not the right person to ask where to get spares even though I've lived in the US. I'm out of date.

I know this an old thread but I just took my 2003 CLK 240 for a service since it had a check engine light. The mechanic told me that it's one of the lamda sensors (As far as I understand my car has 3?) He told me that he can change it but if he orderes the factory part it's going to be expensive/ He advised me to try and find one online even if it's used but still working. The issue is that I don't know if all these sensors are the same or not and I don't know the part number. My car is a 2003 CLK 240 2.6L V6 with 106000KM on the clock.
Any help would be much appreaciated.
