Depends on tires you're running.
Fairly stock tires then look at the factory handling package, and a bit more agressive alignment. Radial tires tend to work better with a bit more negative camber. You can pick that up with more initial negative camber as well as more positive caster. The caster will help the camber when the wheel is turned.

Next steps up would be a bit larger on the front sway bar and/or t-bars. If the car has no front sway bar, then that is almost a given that you want to add one.
I suspect Andy's book would be a good investment on the specifics whether you stay with factory or go aftermarket.
