Create a new plugin using hook location "login_redirect" with the following:

For Usernames (Replace X with the Username of Member being Redirected):

if (!($vbulletin->GPC['logintype'] === 'cplogin' OR $vbulletin->GPC['logintype'] === 'modcplogin'))
{
   if ($vbulletin->userinfo['username'] == X)
   {
        $vbulletin->url = "faq.php";
   }
}

Or for Usergroups (Replace X with the Usergroup ID(s) being Redirected:

if (!($vbulletin->GPC['logintype'] === 'cplogin' OR $vbulletin->GPC['logintype'] === 'modcplogin'))
{
   if (is_member_of($vbulletin->userinfo, X))
   {
        $vbulletin->url = "faq.php";
   }
}
