Google Sitemaps to Google Webmaster Tools
Google Webmaster Central is the portal for webmasters to submit a site, perform simple checks to see if their site is indexed or to create Sitemaps. It also has links to the Webmaster Blog, Google Group, and Help Center.
No, they still don't allow you to manually change your rankings (other than removing one completely, or a new submission). It is a big push toward Google's way of getting the webmasters ties even closer to Google (like we aren't already) in allowing them to focus the way GoogleBot will crawl their site.
