Ad group paused

Hi
Just a few questions for anybody who might know.

  1. In the Keywords section of Google ads my ad groups show ‘paused’ and I don’t know how to un-pause them.

  2. Also should I have my website URL written in after each keyword.

  3. Should I be using all the Gurus or is there a list of absolute favorites.

Thanks, if you know more than me, this is screen shot of my keywords page.
