Do either of those upgrades affect MPG? I have no idea - (newbie question)
The crank pulley has been known to add a few mpg. The tires obviously too, though going any more eco than what is stock and you won't have nearly as much traction as I feel comfortable with. The thicker sway bar is merely there to correct oversteer and lower body roll.
