my entire suspension is totally shot

heres what im planning on
bat rear swaybar (aussie GB is taking too long)
rear poly swaybar bushings
mod rear subframe (dad is a welder)
rear strut mounts
front poly swaybar bushings
new front control arms
front swaybar links
koni struts
new pass side outer tierod (driver side is onyl 3 months old)
now heres my dilemma:
camber plates - do they replace the front strut mounts or are they just an add on?
springs - i dont know which ones to get. i would like coilovers, but im not sure if i really need them. also they are expensive. i want a mild drop but not slammed. i do like the idea of being able to adjust the coilovers though. my main concern is performance, im not going cheap on anything, right now my car is scary to drive past 50mph, can barely control it!
strut tower braces - do they really work? are they worth it?
any comments/suggestions please. is there anything i forgot that i should replace?
thanks,
Russell
