Spring/Shock probs, Clunks, pops, groans, creaks, squeaks Options

So over the weekend I spent about 17 hours installing new springs (Eibach 1.5's) Shocks (GR2's) and sway bars (ST). It's easy once you know what to do, but the sounds coming out of the car are horrendous. The rear clicks, pops, and feels like the whole back end is gonna fall off when I go over a bump, like the shocks aren't doing their job or the springs coming loose or something. The front used to make clunks when I turned, but that was fixed by realigning the "out" arrow with the steering knuckle bracket. It now makes some noises on the freeway, and also when you push down on the car. It creaks when you do that. Also, I didn't have to compress the rear springs to reassemble the strut. Meaning, I could turn it slightly when it was in the car, while it was raised. Obviously it doesn't turn with the weight on it, but over a bump could it be coming loose? When I took the stock rears off, the springs were compressed, and I was unable to move them. Am I missing a washer somewhere? I didn't see any when I took the strut assembly apart. Any help is appreciated.

Okay okay, so it's still making the clacking noise on the stock springs with the KYB shocks. I tightened down the nut on the damper shaft like crazy, could that be it? Too much torque on it? Here's the situation. With the stock springs on the new struts, I can bounce it on the ground and it won't make a noise. With the eibach's, it makes a clacking noise, because the strut mount hits the springs cuz the springs are coming off. I just saw a layout of the rear suspension, and I'm not missing a piece. I don't know wtf is going on.
