Hi, This ones easy. You can check if a site is indexed by searching Google for the following
site:gotelepresence.com - there about 170 pages from the site indexed.
A site's Google Page Rank is earned over time. You can check it here

The scale is 0 lowest to 10 highest. It's an authority scale assigned by Google.
People sometime search particular terms to see what page their site is listed (ranked) on Google. For instance if you search whypark, my blog is on the bottom of the second page (moved up from the ninth page from one month ago)
