Should I be using drupal?

Will it improve it? That depends on how you put it together. Drupal will make it easier to add new content and to reorganize what you already have. But it won't rewrite the content or weed out useless stuff. And certainly, Drupal opens up a number of new opportunities, such as user-submitted content.
