Well mitch if your looking at keeping your car for the long term then a zorst & set of extractors r a good start with a hiflow cat converter + with a little more power u might want to look into a lowering kit shockys & springs sway bars +
watch the rear control arm bushings they tend to wear out & split & you get free movement of the diff.
Ball joints/control arms on the front are another area to watch/check too if the car has been driven hard the ball joint shockets will have free play around the ball joint making it look like u have floged ball joints but is really the arms.
How ever the arms can be sorted with out new items being sorced by way of welding the ball joints in place I would not recommend this being done if you have the money get a set or one from the wrecker
Hope that helps mate
Mike
