I'm posting my opinion on this about a year after the last post on this thread, but maybe it will help someone.
I purchased the Infinite Skills AutoCAD Electrical DVD and found it of limited usefulness. The instructor appears to be very knowledgeable about straight AutoCAD but is clearly not well versed in electrical drawing work, except at a rudimentary level, so his tour through AutoCAD Electrical has electrical drawing examples that just don't make sense which is quite distracting. As a result, he cannot provide practical insights or advice on how to actually use ACE in practice.
I found a better tutorial video series:

It's a better introduction and overview from a person who appears to have actually used the package, so I found it more useful. However, keep in mind that it is just an introduction and you will have to look elsewhere for more detailed instruction.
Experimenting on your own, reading the manual, visiting the AutoCAD Electrical user forum at AutoDesk and asking the ACE specialist who works for the vendor that sold you the product will prove useful.
AutoCAD Electrical does have a pretty steep learning curve, but once you've invested the time to get proficient with it, you'll find it will save you a lot of time. I've been using it for about a year and and still have much to learn. However, I'd never go back to using straight AutoCAD. The productivity gains with AutoCAD Electrical are something I don't want to work without.
One last thing: while AutoCAD Electrical runs in the AutoCAD environment, it's best to view it as a completely new and different software package. Learn and use just the AutoCAD Electrical commands, as they have many advantages over the straight AutoCAD commands. They do an awful lot of the work for you that you would have to do manually otherwise.
