Best practices for body area navigation, Like Drupal Downloads page.

Hi -

I am curious about the best way to implement a tab / sub-tab navigation similar to this in the body area:
http://drupal.org/project/Modules/4.7

Couple things I need, that this does:
1) The parent tab (ie modules), has 5 unique children - change the parent tab and related sub-tab children display.
2) The page content shown on a child page (ie 4.7.x) only displays content that is relevant to the parent/child combination.

Are you achieving this with just the taxonomy module?

Thanks for ideas/links to investigate doing this.
