Create additional address lists on Exchange Server

We are in the process of adding additional departmental address books to our exchange server with the end goal of controlling access to various contacts and user accounts. The goal is to then allow users to sync their Blackberries with the departmental address list they belong to. They in turn would not have access to other departmental lists nor to the Global Address list. With that my questions are:

1. Creation of additional address lists - recommended procedure?
2. Assignment of access rights to both the new lists as well as the GAL.
3. Ensuring that the new lists appear in the users Outlook (Outlook 2003).
4. Syncing Blackberries with the appropriate lists.
