Adam,
If you are interested in a Workshop for Film/Video Cameras try The International Film and Telivision Workshops in Rockport, Maine. I took a Steadicam workshop about 10 years ago.

As for focus for a film job I also own a Bartech Focus Device (BFD).....or as its other wise known...the BIG FUC*ING DEAL
It is a great system you can run the Jib motors with them or a Heden. It is very easy to calibrate
and it has been entered for a Technical Academy Award. I use it on the Jib on Video jobs also when the DP want to pull focus....we also rent them out.
