how would i go about creating variable menu links I would like to display different menu links on each page depending on the content and relevance of each page. How would I do this?
You should try Context   


  Context allows you to manage contextual conditions and reactions for
  different portions of your site. You can think of each context as
  representing a "section" of your site. For each context, you can
  choose the conditions that trigger this context to be active and
  choose different aspects of Drupal that should react to this active
  context.
