The Hanlon video is a great resource, worth every penny, but it's got a couple of minor flaws. Mainly, it's on an older trans with a completely different reverse helper spring setup, and without a reverse shaft brake/synchro. Neither are that hard to figure out on your own. We also doesn't tell you you should have marked the positions of the sliders on the hubs until he's showing you how to reassemble them.
Here's a fantastic writeup to work from too:
