Sitemaps and SEO plugin - Where to look for sitemap

I have recently created Wordpress network using the multisite feature in WP 3.0.4. I had the original Google XML Sitemap Generator plugin installed and my original sitemap is available at mysite.com/sitemap.xml and it is still there. I want to know where can I see the sitemap generated by the Sitemaps and SEO plugin from WPMUDev and is there an option to change settings and priorities.

Also, do I need to unistall the original Google XML Sitemap Generator plugin.
