I need 3 changes in the Brushed template (free one page template)

I am working on the free brushed-template, so I have no license key that you need to submit a question on the themeforest side. So I try it in this forum.
3 things I wnat changed in the template :

  1. click on the bottom-arrow to go to the top must go to the first page (so not completely to the top, but href-code does not work
  2. the popup that appears when clicked on a work shows a picture and text that is taken from the alt-text. I want links in this texts, so I want the popup-text from a different source. How can that been done?
  3. would like submenu’s in the work-images, is that possible?
