Fill your frames with your photos. They can still be changed if you decide you would prefer a different one but go ahead and do the best you can to pick photos you like.
Start by hanging one frame and working your way until you have recreated the wall you made on your floor. I think this is definitely a two person job, to make sure things are hung straight and to hand the other person frames and nails to hang.
All gold hues with mirrors, a giant T and some cool keys!
I also did it more "randomly" then the square arrangement I now have in my apartment.
