Features.module is an extremely powerful tool for managing Drupal configuration changes.
Content Types, CCK settings, Views, Drupal Variables, Contexts, Imagecache presets, Menus, Taxonomies, and Permissions can all be rolled into a feature, which can be checked into version control. From there, deploying a new site, or pushing changes to an existing one, is easily managed with the Features UI or Drush.
Make sure you install Strongarm.module for exporting drupal config that gets stored in your Variables table. You can also static content/nodes (ie: about us, faqs, etc) into Features by installing uuid_features.module.
Hands down, this is the best way to work with other developers on the same site, and to move your site from Development to Testing to Staging and Production.
