shadow,
i installed the springs and struts/shocks on my '01 not too long ago. it's not a hard job, but it does require some patience. getting those rear springs out was not the easiest job to do. i had an easier time with the fronts.
camber plates are NOT required and neither are the offset rack bushings or x2 ball joints that everyone says you must have when lowering the car. if you're just using the pro-kits, then you're okay. if you use the sportline, then i would consider the ball joints. i remember talking to eric at XMP about the bushings and IIRC, he said we didn't need them.
i had camber plates installed only because i installed the bilstein sport struts/shocks and they're OEM for the cobra r.
