I want to be able to switch between a 9v battery, 8 AA's in series (12v), 9v from a wall-wart, and off.

left switch switches between the 9v and 8 AA's. right switch switches between using batteries, the wall wart, and turning off. Would my layout do this?

btw I don't know if my terminology is correct. +9/12v means positive lead, 9/12v gnd means negative lead. same with the dc in/gnd. V_s would be the voltage going into the circuit, and the wire opposite would go to the circuit's ground (the one I marked with the three lines)

Looks good to me. Someone else have a look though, I don't want to be responsible if it doesn't work.
