There are some pretty good technical webcasts available on IBM's Tivoli Support site:
If you haven't already found these they are a bit helpful for those topics you are new to in the Tivoli software. Some are very broad in scope and others are fairly granular. Check these out if you haven't already. I try to visit this site a couple times per month to register for the upcomming webcasts. Whats nice about joining a live webcast is that you can ask relevant questions at that time. All the old ones are posted.
