What I noticed is that you do not have much toe compared to where it was before you started. When the toe gets close to straight up, the front will become "darty", especially as speed increases. If you want the car to push a little, toe in the front more otherwise toe out the front.
As far as the camber shims, leave them out. The car comes with way too little camber and you do not have that much anyway. Those that really want some performance push the camber to greater than 2.5 degs.
Also, the next time you have an alignment done, by factory spec, you are suppose to put weight in the drivers seat. This changes the ride height enough to change the alignment by adding 150-200 lbs in the driver's seat.
