I've done pads all the way around on ALL of my MBs, and I will attest to the ease and serviceability as well.
It's gotten to the point where I have my 8-yr old daughter helping out. She gets to pound out the pins (300E and SL500), pull out the old pads, and when I get caliper clearance, put the new ones in and pound the pins back in. Now she eagerly tells her friends that she knows how to do brake jobs!
The most exotic tool I use throughout the process is a punch...your particular model MB has the pads held in place by pins that have to be driven out...
..oh yeah, if the brake kits don't include paste, buy some and apply sparingly on the piston side of each pad. Keeps the brakes from squealing!
