Decided to install a named instance just to go through the process again.
There is a hyerlink in the Successful install page http://go.microsoft.com/fwlink/?linkId=87843 for the version specific SQL Sample Databases. And there is an installation summary that you can review as well, that comes up in a notepad, with machine properties, product features discovered, package properties and user input settings. This is all saved in a configuration file on c:\Programfiles\ microsoft sql server\100\setup bootstrap\log\a variable here\systemconfigurationcheck_report.htm
I also found some great resources on SQLskills.com - like corrupted databases... and MP3's on some Master SQL topics that I can listen to on my little mp3 player while working out. I'll post on the back ups later.
