Cuban is right. And the wifi/4g/gps widget is switchpro from the market. I've uploaded the zip of the icon set. I'd direct you to the post, but I don't remember where it was.
Most of these Walls can be found on this thread, Zedge or Backgrounds app.
Most of these widgets are linked in the previous pages. Lot of reading but it's worth it you will learn a lot!
This launcher is called Android Seven. I't the free version, so it doesn't have all the features and it has ads... I'm not keeping this setup, just thought it was cool.
