I started out with Awesome as well but switched to i3, get a huge amount of functionality out of a very straightforward config (read: low PITA/high reward factor).
Anyway, for a very nice gtk3 look you can try StudioFlat off of the Gnome Look site, and gnome-icons-brave via whatever your package manager happens to be.
The tiny xcalib package (100kb) is also worth grabbing, hook up to xbindkeys and you get screen color inversion _per monitor_, very bad ass, your eyes will love it.
