Replace all your bushings first. It will amaze you the diff you feel. Try to find hard rubber if you can. Then better swap bar and coil overs or a shock spring combo.
I have well over $1000 into my beat up suspension and still not too happy with it yet. I wouldn't replace all the bushings, but I would find out what ones have issues. lower control arm bushings are almost always beat up by this age of a car
