Yep however there are flight states which cause the initial stalled region of the wing to be further outboard.

Consult your airfoil's lift polar before relying on rules of thumb about its behaviour...
Yep, I certainly recommend checking out lift coefficient vs angle of attack plots with different control surface or flap deflections to see that the stall AoA is reduced with downwards control/flap deflection.
