If your car came with an owner's manual, it will do a good job of pointing all that out. If not, pop in to mbusa.com and your can either order or download a manual--great place to start.
The smaller lights low in the bumper will be your fogs. When you have low beam headlights on, you can pull the light switch out to turn on the fogs. Try it, then get out to look. If you flip your high beams on--fogs should turn off.
If i read your question right--the little panel between the lights (if below) might be headlight washers.
Unless the original light fixtures have been changed, your headlights are likely halogen (not xenon). If so, probably an H7 bulb--but know what you have before you try to change it.
