Because no address book data from a BlackBerry can be sent via bluetooth for security reasons, I don't think you'll get the address book info (and hence, caller ID) on the car's dashboard. But the handsfree part should work fine.
i have a TL. i see the phone number of incoming calls in the display area of the dash, but of course there's no name information displayed there. the TL's phonebook is not at all connected to the BB's.
