I'd run a separate circuit for the outside lights and receptacles. That way if there's a problem outside none of the circuits inside the house are dead.
I would install metal boxes on the exterior. You could use deep gem boxes and use the metal brackets to hold them in place at the right exposure. If the stucco guys bend the edges of the plastic boxes hen they're troweling the box would be wacky and the only way to get it back in shape would be to spend the time to chip out the errant stucco.
