Add administration menu item for one role only
I can get a custom menu item showing up in the admin bar, but how do I get it to redirect to another page, and how to I stop users without the role from seeing it?


You can set the page callback to drupal_goto, pass the redirect path and other arguments as page arguments, and use the access arguments to set permissions.

I love admin menu, but I'm not sure it's something I particularly like putting in the hands of the clients. It's easy to find yourself giving too many perms to the client, and you can't use the menu module to add items to it. I've not used it yet, but on my next project I'm going to try something like SimpleMenu.
