If you're going to do one swaybar do the rear. The car will turn in better then both, but it might feel irregular to someone at first.
The front only will cause the car to feel like it'* going to pickup the rear inside wheel when turning hard. Get endlinks and sway bars if you want to kill roll, springs should be chosed based vehicle weight, height (drop springs or not) and such. Stiffening the ride to hell to stop roll is the wrong way to approach this. Euro cars are setup with great sway bars and good (not stiff) springs.
