I'm not sure about questions 1 and 2, but for 3 and 4...
3. Look at SQLFORM.grid in the book

4. You wouldn't add them to 'membership' admin, but to 'group' admin.
Something like db.auth_membership.insert(userid=999, group_id=1234) where
999 is the id of the user and 1234 is the id of the Admin group. See here:
http://web2py.com/books/default/chapter/29/06/the-database-abstraction-layer#insert
for more info on inserting records and
here:
http://web2py.com/books/default/chapter/29/09/access-control#Authorization
for more info on authentication and authorization.
