You probably won't find anything as far as videos, etc.. for NCL. The learning curve is steep if you come from almost any other cam system, and the help files that come with it really won't help you much unless you know the system.
If you want to make progress your company really should send you to a reseller or to NCCS for instruction. The basic course is a week long and highly recommended to avoid floundering around while attempting to learn on your own. Ask your boss if he can give you a copy of the Pocket Reference Guide.
