I meant get some good shocks i use bilstein and use the springs you have. You can adjust the height with the bilstein shocks and they will be cheaper than s/h coilovers.
Caster rods allow you to alter caster. More caster will imporve turn in, up to a point, but makes steering a bit heavier. There bushers in the rear are important as well, i replace 4 in each side.
I make the strut braces myself, i can email you a pic if your interested.
