I agree. Start with Walls, Doors, Windows and Grids. You can gain productivity from this alone. I have setup many companies with ADT and the biggest mistake is trying to do it all at once. (There is a ton of free up to date ADT Video tutorials at
www.dgcad.com )
Then create
Network Palettes for single point control of all of the content above. All users wiil see the same palettes and it's controlled by the CAD manager. This is KEY.

It ensures office standards, consistancy across projects and ease of control.
I have just published 3 great Video Tutorials, that are getting great reviews, on how easy you can network your palettes. See three links below. (right click the link and click 'save target as' to download.
