Jess,
I noticed that nobody answered. So, time for the "B" team. Having seen this question come up, a couple of notes:
Sounds like you've already found the pdf manual in the AS9 CD? It's not sufficiently thorough / rigorous, but a good couple hundred pages of introduction .
If you look back in this forum, someone has a sort of manual, called something like "hands on a house" which it appears is good but for an older version.
One can learn a lot by reading useful looking past posts of this forum.
Other than that I don't think anything exists. And several have said that AS is too different from AutoCAD & AC LT for those to be useful.
