SharePoint End-User Training
Microsoft has released a standalone version of the end-user training for sharepoint. The overview below describes it in more detail but it seems to be pretty good for a first time user getting started with collaboration in MOSS. There are click-throughs for many of the topics however they are obviously not as interactive as the portal edition of the training.
It can be downloaded here:
