interesting, google wont shows a website linking to you unless it is Pr5 or above... the easiest way to get indexed yeah just submit your sitemap.. but the truth you don't even have to do that if you have strong links pointing to your website.... google will crawl you natural and index you automatically, we have over 700 sites indexed in google and have never used their webmaster tools or submitted a sitemap.. we rank on many many pages... intriguing isn't it!!!
