as far as the shimmy goes you may want to make sure that you didnt damage anythign when putting it all back together, keeping in mind to not torque down suspension components until they are on the ground.. mine had 211k when i put them on, and since then ive pretty much changed all bushings and links except for a couple on the back.. trust me, they WILL get worse with time unless you change them now.
Ive got bilstein sport shocks with eibach springs.. turned out perfect.. it can get harsh over big bumps but overall its not too bad.. you want to double check your shocks.. replace those if you have to..
