How to use Drake

Here's what I want to do with Drake: I want to add a menu item in Drupal that only admins have access to. This menu item will link to the cakephp app that will allow admins to add products to a database. I have the drake piece setup and I can go to ?q=drake and see the page. I'm trying to get the menu to display, but nothing is working. My Admin site uses chameleon theme, so I looked at chameleon.theme and see it uses theme_blocks('left') to display the menu, but this doesn't work for me. So...
1) should I be able to display the menu?
2) how do I do this?

Thanks for any help,
Paul
