Object undefined in jquery, plus my links are pointing elsewhere
The Drupal JS object not being defined is a symptom of it not loading core JS files. His previous site probably enabled JS aggregation that places the aggregated file in sites/someothersite/files/XXX.js. The same goes for the missing images. Have you copied over sites/someothersite/ from the previous host? 

It sounds like sites/someothersite/settings.php was what his original host was using and configured for DB &amp; files. Since you're now viewing the site on  gator1111.hostgator.com Drupal is using sites/default/settings.php. 

This primer on drupal multi-site settings might help to also explain what's going on.
