Work backwards. Leave installing and configuring it for last.
In my experience, the best way is to hand your colleagues a working configuration (vApp will make your life easy). Have them learn the product from a basic end user perspective first.
Then when they're comfortable creating and managing users and roles, introduce them to the /immanage console and all that's involved there. Have them create a IMS Directory and IM Environment. Export roles and that sort of thing.
Finally have them learn about the installs and all the server component pieces.
