Are you talking about getting dressed or the long term assembly of parts?
I have seen several dressing videos of Boba Fett and to tell you the truth they are very similar. I have never taken video of myself putting the kit on though.
I attach my armor to the vest with snaps and velcro. The thighs are a complete set with the ammo belt on my kit.
I attach the gauntlet hoses to the flightsuit with a small parachute clip under the double sleeve............

These are old pics and I have continued to improve the kit over the years but it gives you the basic ideas.

Knees are attached through slits in the flight suit with an elastic band ran around the back of the knee on the inside of the flight suit so that it is not visible.
You can also check out Cruzers thread. http://www.thedentedhelmet.com/f28/jango-build-member-51906/ He has lots of great pictures and pretty much runs through the full assembly process. Between Mullreel's post above and Cruzers thread this should answer most if not all of your questions.
