I recently updated our web site from static HTML (http://archive.firstbaptist-manlius.org/) to drupal (http://firstbaptist-manlius.org/).

For right now I am trying to keep the list of modules as low as possible to keep maintenance easy.

FCKEditor (for the couple folks that may actually help maintain the content, but are not HTML guru's)
nodetype (Right now most of the content is on "pages", but as new people come in to help, I'll be able to switch the node type to "youth page" or "missions page" for users to edit those node types)
pathauto (for nice clean urls)
