BB Bold 9700 :: Edit My Address Book - Manipulate Numbers Easily On Mac Computer

I am brand new to Blackberry and am trying to edit my address book. All the telephone numbers from my old Mobile Phone have been imported to my Bold, but it’s labeling them all as “Work” contacts, which isn’t true.
How can I manipulate these numbers easily on my Mac computer? I downloaded Blackberry Desktop Manager for Mac and have backed up the contacts (as a bbb file, I think). But still finding it difficult to actually see the phone numbers and manipulate them on my computer.
