Creating Custom Password Reset Form

I guess I have a strange request, but I know there has to be a way. I have set up a custom registration form that handles Name, Email, Practice (medical), Phone and Password. All this is stored somewhere in the back-end, I just don't know where. Here is what I need to do:

Taking advantage of gravity forms and the wp-login.php files, I would like to find out where the custom userdata of gravity forms is stored, call those functions into the wp-login.php file where when a user requests to reset their password, all the custom Gravity Form info user data is sent to the admin of the site in a wordpress-generated email:

[php]
$message = __('Someone requested that the password be reset for the following account:') . "\r\n\r\n";
	$message .= sprintf(__('Username: %s'), $user_login) . "\r\n\r\n";
	$message .= sprintf(__('User Email: %s'), $user_email) . "\r\n\r\n";
	$message .= __('If this was a mistake, just ignore this email and nothing will happen.') . "\r\n\r\n";
	$message .= __('To reset your password, visit the following address:') . "\r\n\r\n";
	$message .= '<' . network_site_url("wp-login.php?action=rp&key=$key&login=" . rawurlencode($user_login), 'login') . ">\r\n";

So the admin gets Name, Email, Practice, and Phone and the new password of the user requesting the reset. Right now I just have username and email.

Secondly, I want to learn how to use custom queries to auto-populate the Phone and Practice fields in the contact form (as I don't know how to), separate from registration form, so when a logged in user wishes to contact site admin, their fields are already populated for them according to the info they inputted when they registered. I realize this is a common question on these forums, but I still don't understand what needs to be done code-wise...

So yeh, mainly I just want to know where I need to go to access the stored info gravity forms keeps of registered user data, then I need to call that data to be sent through email to the admin when a user resets their password. My client (the admin) wants to have all that information. And lastly, need to know how to create a query for auto populating fields: Phone and Practice.

Thanks! Hope that makes sense.
