I agree with Grimace (I seem to do that a lot). As far as what to change it really depends on your goals for the car and how you plan to use it. For a street setup I would add un adjustable upper control arm and some good dampers (Tokico D Spec adjustables, our Pro Actions are a great choice for nondjustable).
Beyond that, the sky is the limit, you can build a Watt's link equipped corner carver, a drag car, or anything you really want. Set realistic goals first, then choosing the parts will be easier as you'll know what fits with your plan and what would not be a good choice. IE if you plan to drag race you may want to add an anti-roll bar, but you won't want upgraded sway bars.
