Welcome to the Q&A Forum

Hi there, I do not see any bylines on your site, nor content where there would naturally be a byline (e.g., feature articles and blog posts.) Authorship is, well, for individual authors -- while Publisher is for brands. Do you have a Google+ brand page? If so, you could verify it and add the Rel Publisher code to your page. This would increase (but not guarantee) your chances for showing up in the Knowledge Graph. To establish Authorship, you have been given a lot of good advice -- but you need to create content that is appropriate for Authorship as I mentioned. Hope that helps!

no, but the sentence "Guaranteed page 1 Google Rank" says enough to me.

No, the meta description tag has no effect on rankings. It could affect CTR if someone things it's an outdated article if the date displayed is old.
