Dakota,
Alas, I have no recommendations re CD training, but IMNHO, two first-rate texts that may be of benefit. The first is The Little OS Mac OS X Book by Robin Williams and the second is Mac OS X - The Missing Manual (Second Edition) by David Pogue. Both are available at Amazon and elsewhere.
I also recommend you do a Google search on "YMUG Conceptual Guide To Unix". That will go to a link allowing you to download a 27-page pdf published by the Yorkshire Mac Users Group.
Yeah, OS X is a bit a transition and most of us have had our days of expanded vocabulary. But then, most of us are also glad that we have made the switch.
So come on in. The water is not all that deep, there really are no sharks lurking about, there are several lifeguards around (just in case) and, you are with friends.
