Art,
I know that Richard Ritter has some workshops, but I don't know if any are for beginner LF use. Carl Weese is up there, his workshops are more for pt/pd printing, but they are worth a look. Maine Photographic Workshops runs a few each year that would probably be suitable.
Look for some workshops at the Peters Valley Craft Education Center (northern New Jersey). They run a bunch each year, and should have an intro course.
Look at your local community college, they sometimes have this type of mini-class to offer. If you are willing to go further afield, there are many, many to choose from.
I do strongly encourage you to go the LF Conference in Springfield next year, as it will give you the opportunity to see lots of LF discussions, photographs, and equipment from vendors. There is no doubt that the vendors section is the best opportunity in the US to actually see and try out some of the equipment that you may have read about in the magazines or on the internet. That alone is worth the effort to get there.
