Acquisition Manager - A few Questions on basic structure

This is my 1st time working with Acquisition Manager. I want to be able to associate my Prospects to a List and to other attributes (Catholic, Non-Sect, Spanish) + I have a few questions on some of the Prospect fields.

1. Prospect ID - this needs to be unique - what values are typically populated here? Can this field remain blank?
2. ListName - this is where I would like to add the List# but I see that this really is the iMIS Mermber Type. Where would I insert the List#?
3. Full Address and Zip Code - these are missing from the Prospect Table.
4. May I go into Business Object Designer and add additional columns to the Prospect Table?

I realize that once these names are added to iMIS - I will have the above functionality - but initially I will not merge these names into iMIS.
