Found some high level information on how to add new custom fields to the user registration pages but still in the dark. Specifically, I would like to

1) Add fields to the New customer registration page. (1 basic text field) and store it in the database. Can anyone point me to the .ascx file to modify and how it would be done?
2) Also, code to retrieve or display this data later on...
3) Place email verifcation on the new user account sign up to verify email address. (User must authenticate by checking email after registration).

Any help appreciated.

You need to modify ConLib/RegisterDialog control files.

2) Also, code to retrieve or display this data later on...

For custom data with user you need to make use of user settings. Read following thread about how to save/retrieve data from user settings.

3) Place email verifcation on the new user account sign up to verify email address. (User must authenticate by checking email after registration).

Read following thread about how to implement verification support.
