I think (if I understand you) you can do what you want by creating a plugin using hook location login_redirect and setting $vbulletin->url to what you want. For instance I was able to make it so that admins go to the CMS page by using this code:

if ($vbulletin->userinfo['usergroupid'] == 6)
   $vbulletin->url = "content.php";

I know this isn't the programming section, but maybe this will help if you can't find an existing mod.
