Outlook for Simple Database?

Hello All,
    I am working with a non-profit who currently has a database with about 700 names.  There are many custom fields in this database. They ideally want to tie this database into quickbooks. They would like to use Outlook as their primary CMS. Is there a way to do the following?:
1) Design custom forms for all their custom fields in their current database?
2) Import the database?
3) Share the Contacts between all the computers in the office.

They are all running Windows 7 and Outlook 2010.
