Workshops are available for free from the Apple retail stores.
Look at their sites for schedules.
The Advanced iPad workshop and the iCloud workshop provided a number of useful tips:
iCloud provides storage for files and pushes them to your device with free 5GB (see http://www.apple.com/icloud/)
New photos are stored for 30 days
Install on PC by search for iCloud for Windows (XP doesn’t support it).
Word processing documents in iCloud require Pages app ($10).
Documents are not shared with other people, but calendars can be.
Mail will be per an added me.com address.
