Why does this seem like a loaded, baited question?
[ QUOTE ]
In the situation of base turning final, overshooting, jam on bottom rudder and stall / spin: does the bottom wing stall first or do both wings stall at the same time with the bottom wing more stalled?

I've always thought the bottom wing stalls first. If you have an appreciable roll rate, it may just be enough to push the relative wind on the "inboard" wing past its stalling AOA. Also, the outboard wing is moving a little faster through the air, so it may have just a hair more freestream energy to keep the flow attached.

Also, does stall speed rise when flying uncoordinated?

I'm gonna go out on a limb and say, "no." Break the relative wind into two components: perpendicular and parallel to the chord of the wing (not counting swept wings here). The lift keeping the plane in the air is generated from the flow perpendicular to the wing. The airspeed
should measure only the chord-wise component of the flow, so the indicated stalling speed shouldn't change.
The spanwise flow, that doesn't generate any lift but lengthens the path could become a factor in extreme cases. After the flow over the wing has traveled a certain distance ("characteristic length"), it is apt to transition from laminar to turbulent. Because its flowing diagonally compared to the lifting surface, the flow may become turbulent at a shorter distance along the chord and effectively reduce the efficiency of the wing and generate less lift.
Maybe I'm full of it?
