I found from other post about theming user login page/form.
One method for theming full layout of a user login page is simply copy page.tpl.php to page-user.tpl.php

I tried on garland theme and it works but not on ninesixty theme.

Make sure you have the page.tpl.php in the same directory as page-user.tpl.php. This is a known core issue but NineSixty will remedy this in the new version.

Install Theme Developer Tool in order to visualize the source of your output. This tool even gives you suggestions on using the overrites http://drupal.org/project/devel_themer

Also, remember you must Flush Drupal Cache every time you set an override because of the theme registry.
