For the username check...

Form Hook: Before Submit:

PHP Code:

$checkuser = $vbulletin->db->query_first("SELECT userid FROM " . TABLE_PREFIX . "user WHERE username = '".$vbulletin->db->escape_string($q['username'])."' ");
if (!$checkuser['userid']&&$q['username'])
{
$preview = true;
$complete = false;
$inputerror[344] = '<font color="red">Invalid Username</font>';
$incompleteqs[] = $qn['username'];
} 


Change 344 to the question hash

and make sure the Username Suggest question has Reference Name of:

username
