You already have the most important skill to take to any new adventure -- you know how so say that you DON'T know.
You might be surprised how many folks just don't seem to competent in admitting that they came to learn from the beginning. I watched a self-proclaimed expert dump a $45,000 camcorder right on the lens because he didn't know that he needed to latch it into the "shoe" on the tripod, and his ego wouldn't allow him to ask. I also had a TRUE world-class expert shooter ask me for some minor detail on the camera he had borrowed, because I was using the same model and he figured that I knew more about it that he did.
When you go to the workshop, watch what other people do and whether it works or not. Don't claim a moment of experience that you haven't got, because if they assume that your skill is at a certain level, they won't mention something that they figure you already know, and they may use jargon that you don't understand, leaving you lost while they move on.
Most of all, HAVE FUN and PRACTICE. I'm having a blast playing with my Pilot and EX1R, a highly-capable, complete system that weighs less than the Sony shoulder rigs that I used when I got started (so far back that we logged our shots on stone tablets). Don't worry if something doesn't sing to you the first time you try it, keep going and eventually it will be as second-nature to you as it is to the instructors.
