Help with Security Assist

Dear Support Team,
Have some questions regarding Security Assist.
1) Can I customize the Registration form generated by Security Assist such that I can include a field that contain Security Challenge Questions that must be answered by user, and the answer stored in the database? If it is possible, can you please help with the steps to accomplish that?
2) Can I customer the Email Password page generated by Security Assist to include the same Security Challenge Question field as above such that each time a user wants to retrieve the password, the user must give a matched answer to the security question stored in the database before the password can be send to the user? If it is possible, how can I do that?

3) How can I customize the login Page such that each user can login and be able to view only information belonging to the user for instance, read email, view grades, etc? Do I need to include a special column in the database to retrieve the information?

I will appreciate if you can help me with all those questions
