My company, Ledet Adobe Training, has provided formal, instructor-led Scripting training in the past several times (probably 3 or 4) but there's not enough demand to put it on a public schedule. If you are looking for a quote for a private class, you can fill out our quote request form at http://www.ledet.com/request/new but it's really only appropriate for groups. Something like this would typically run around $6K and up for a two day, plus travel.
I meant to reply weeks ago, oops! Time flies...
Thanks for the confirmation of my findings. I've actually been making a lot of leaps and bounds in understanding what the heck I'm doing. Some of it still seems a bit black magicky... but I keep looking back at attempted scripts and realizing I've learned enough to bring them up to speed.
So far my projects have been working out pretty well, and I'm getting to the point where I can write solid sections without any reference.
Reading through the comments & examples has been instrumental (sometimes if only to point me in the right section in the reference manuals!).
