As for the sitemap problem, see if this helps. In vault/special_class_friendlyurl.php, find:

		return $urlinfo['url'] . ($query ? $amp . $query : '');

Replace with:

$url = $urlinfo['url'];
		if (
			(
				THIS_SCRIPT == 'cron' OR
				(
					VB_AREA == 'AdminCP' AND
					strpos($_SERVER['PHP_SELF'], 'sitemap.php') !== false
				)
			) AND
			$GLOBALS['runner'] AND
			is_subclass_of($GLOBALS['runner'], 'vB_SiteMapRunner')
		)
		{
			if (strpos($url, $this->registry->options['bburl']) !== false)
			{
				$url = str_replace($this->registry->options['bburl'] . '/', '', $url);
			}
			else
			{
				$thirdpos = strpos($url, '/', 9);
				$url = substr($url, $thirdpos + 1);
			}
		}

		return $url . ($query ? $amp . $query : '');

It's not a perfect fix, but I think it should catch most configurations. It's not really possible to fix completely because vBulletin didn't give us enough hook locations to work with.
