What is the template name for www.mysite.com/user/login I have literally tried every combination possible, what am I missing?

page--user--login.tpl.php
page--user.tpl.php
page--login.tpl.php
user--login.tpl.php
page-user-login.tpl.php
page--user--login.tpl.php   ... if you create one, make sure you flush your cache!

Also, check out this module: 
https://drupal.org/project/devel_themer     

It'll help you determine these sorts of things, just don't leave it running after you're done development!
