Haven't done brakes on the Mercedes yet, but have on other cars. Its really useful to use jackstands to take both front or back wheels off at the same time (you don't want to work under a car on a jack anyway), that way you can bring both rotors to be turned at the same time. You can get small jackstands for passenger cars for around $40/pair, and they don't take up much room when stored. Throw in a flat piece of wood and you've got yourself a coffee table!
Disk brakes are pretty easy, but you may need a c-clamp or something to push the caliper piston back into the caliper, since your new pads will be thicker than the old ones, you'll need the extra room.
If you've got a second person handy, have them pump up the brake pedal while you bleed...I like that better than the one-man bleeders anyway, but that's just my preference.
Good luck.
