The Pathauto module generates URLs automatically depending on the path provided for each content type specified, and the title of your content. It also does iteration so you can drop out unneeded punctuation and words. Don't forget to create a new path when you setup a new content type, otherwise it will create the default path for all nodes.

The CCK module is another must have Drupal module. It is used to create fields within your content page for specific content to be displayed within the node, or other nodes. It also interacts with many other modules and is one of the building blocks of a solid Drupal website. There are many sub-modules for the Content Construction Kit, and unfortunately, they are all separate modules.

Part of CCK is moving into Drupal 7 core and is known as Fields in Core.

Administration Menu is one of the most useful modules for any Drupal webmaster. Because of this, you will find it to be on the top or near the top of any top 10 Drupal module list. It brings all of the most important sections of the back-end of the Drupal server together with an easy to navigate CSS menu. All Drupal Webmasters, Admins, and Moderators will want to pick this module up for your Drupal server. It is always the first module I install to cut down the time it takes to do everything else on a new Drupal server install, or to modify an existing server install.
