I gave a talk during the 2009 edition of the uber fun DrupalCamp WI event and I thought I would pass on the details of the talk here for participants could have 
a virtual location to rally around the discussion.
Most important, the modules you will want to download and install in your Drupal 6 install are:
CCK - www.drupal.org/project/cck
Views - www.drupal.org/project/views
Rules - www.drupal.org/project/rules
An additional module that extends the Rules module (and many others) is the Token module (www.drupal.org/project/token).
Notes
Once these are installed, administrators have a great deal of flexibility in configuring/creating content on a site, and then display that content in a number of ways that make sense for the specific use case. With the Rules module, administrators can configure a collection of actions based off a triggered event on the site. An example would be: send an email, and re-direct the user after they create new content. Very powerful stuff.
Feel free to add a comment/question if you like.
