To add too what Rainman has mentioned, I have some photo's in my "A TW without Forks is Like a Duck without a Bill" thread that may be of some visual assistance. Though not a step-by-step process, I replaced a buddies fork boots and seals. Later today I will post some of the photo's from the actual fork seal work, though you only mention the boots.
But as Rainman has mentioned, fairly easy to accomplish. I can see where someone would be a little worried about taking the forks off and putting them back on correctly. Once you get started, replacing the boots should only take an hour or two (depending on the number of interruptions) giggle.
Good luck with your "new boots".
