I will go through what I have and see what I can find on leather work. I have done the Tandy starter kit. If you go that route you will get some paper work, a video (probably a DVD now) some starter tools and some cut out projects, that have you put them together and dye. It is fine for an introduction. My friends biggest problems were keeping stuff organized and keeping to leather stored properly. The organization I helped with, by making simple racks to hold his punches and tools and I gave him to old heavy government surplus desks, that he put side by side. The drawers of the desks and the racks kept everything ready to use. His second biggest problem was storage of the leather, we have pretty high humidity on the middle Eastern seaboard. He used to turn out pretty good holsters and slings and made some really elaborate dog leashes for train pointer dogs. After the hunt club he was a part of shut down, so did his orders. Just like any other hobby it can get expensive.
I would contact your local Tandy or leather working shop and see if they would be willing to come and do a demo for your group as part of one of your meetings. That might get you at least an intro to see if you are interested. Or you could ask them if they had a customer that would be interested in showing you the ropes. There might be a local leather club that already set up, that you might attend their meetings or demos.
There is always utube there are hundreds of videos there. What I do is I use a utube copier (YTD) to download them and then a FLV player to watch them as many times as I want.
