How can I edit the spacing between the {search_fields} in search_page_default.html?

Example: From: Field 1
Field 2
Field 3

To: Field 1

Field 2

Field 3

Aslo in testing the site I signed up and was viewing the email verification that was sent.
For some reason I was getting duplicate login information.

Example: Usermane: UserUser
Password: passwordpassword
Any idea how this can be fixed?

Lastly also in the email verification is it possible to change the login?
From - www.mydomain.com/admin/index.php
To - www.mydomain.com/index.php

Thanks for your time
