Not too bad. It helps a lot to have the 'boot removal tool' which is a wrench which levers against the valve cover to pry off the boot. Also helps protect the wires from damage.

Ups, I was dreaming of my 430, which is hibernating until March ... 
Are you sure about 100k miles, I'm pretty sure it's more like 80 to 100k kilometers!
Anyway, I wouldn't go trough the ordeal to change them myself, it's more or less a "one time action" I would recommend, have it done!

Factory recommendation is 100K miles or 5 years on '02 USA models. The OP didn't ask but the plugs would be one of the last things to worry about. Unless there's an issue change them when everything else is sorted out.
Changing them oneself depends on if you have some experience, automotive mechanics tools, the time and the desire to save $300 or so. You do get the satisfaction of knowing you did it yourself but I agree that is likely a one time service for most W210 owners.
