SharePoint 2007 with DoD CAC authentication

1. For Account Name & password, I'm assuming that this credentials are for my local DC.

If you're talking about the AAA profile needed for the AD or LDAP query, then yes the user/pass is a domain account with privileges to perform the query.

1. The iRule all I get is ID field, See pic below. There is now way of entering the anything else.

You need to create a standard iRule that gets applied to the VIP. The iRule event agent in the visual policy will trigger the ACCESS_POLICY_AGENT_EVENT event. In this case the agent's ID value isn't important.
