Newbie here - silly question about the button indicators for 2004 Volvo C70

What is your question?

Just bought a used 2004 Volvo C70, and it's always the little things that get you: the indicator for the fog light button is out. Does the entire switch have to be replaced? The passenger's vanity mirror light is out. How to change the bulb? Or can you? Lastly, is the gear shift supposed to be illuminated?
