Theme Suggestions for User Page
You can use this template for the user page: user-profile.tpl.php

For the user edit page you can take a look at this page: Customize the User Edit page in Drupal 7 - an example.

UPDATE: To add CSS and JS to specific page you can do it like outlined below in a custom module.

/**
 * Implements hook_page_build().
 */
function MYMODULE_page_build(&amp;$page) {

  if (request_uri() == 'path') {

    drupal_add_js( // arguments );
    drupal_add_css( // arguments );
  }
}
