Go into your admin under System -> Config -> Design and under the Package and Theme section make sure you have the theme defined. In your case i'm not 100% when this needs to be set to, as i don't know the directory structure that was installed and i can't find the documentation on the theme forest link you posted.
If you have a path like skin/frontend/theme/name then theme will need to be in the Package area (in the pic i have rwd there, so this would replace) and name would in under Theme in all the areas (if there are not translations you can leave that blank).
If you have a path like skin/frontend/default/theme then you want to leave Package blank and only place theme in the Theme section.
As an FYI, the reason some of the files are trying to read from skin/frontend/base/ is the fallback system Magento uses. If a file is being called from skin/frontend/theme/name/js/somefile.js and that file is not found in that directory, Magento will automatically look in the next package down from it to see if it's there, with the last package being base. So there is no call to a file in the base folder, but since the fallback sees base as the last place to check, the error sent to the browser is for a file with that call. This can get confusing at first as you might be tempted to look for that file in base, but the theme settings will tell you the truth of where files are being drawn from on a Magento install.
