You shouldn't remove the taxonomy on uninstall, as people may be using the taxonomy you created for another purpose, and what you originally intended. Just on the uninstall let the user know that they should be deleted.
If your module defines the content type Drupal will handle the fact that the definition is missing, and the admin can clean up all the nodes, and other definitions.

Now I'm working on the uninstall, and the seemingly infinite cleanup that's needed, not that anyone would ever want to remove my module, once installed!

I don't seem to see a magic function that, given a node type, will remove all associated node data for that type. Also, I think I should remove the files that were uploaded as cck image content. Any tips on a good example of a complete "undo"? :)
