I can't tell you what I've got everything bound to, but I can tell you what I use on a regular basis (and what I'm learning to use):

Normal Use:
1 - 5
Shift 1 - 5
Q, E, R, F, Z, X, C
Shift + Q, E (Strafe got moved to A & D)
Middle Mouse (also paired up with Shift, Alt, Ctrl, Alt & Shift)
Mousewheel Up/Down (also paired up with Shift, Alt)

I'd like to start using Alt more and I just swapped CapsLock and Ctrl to see if it would force me to get used to using that unused modifier... we'll see; and for some reason I always end up slacking on my mouse buttons (G700), but I keep telling myself I'm going to use them one of these days.
