Is it possible you bent a strut? A bent strut would give you caster/caber problems on that wheel, as well as some unpleasant suspension quirks due to the bent strut unable to travel properly.
One way to adjust the caster/camber slightly overall is for the alignment tech to shift the subframe assembly slightly to compensate.
In regards to your steering/pedal shimmy while stopping, did you clean any rust/debris off the hubs before installing the new rotors? If the hub surface is uneven, it could cause the rotor to seat crooked and cause a vibration.
I have also seen a loose CV shaft nut cause vibrations due to the wheel bearing coming loose slightly inside the steering knuckle. As a result,, the hub tilts off center, causing a vibration. You could try checking the torque on your axle shaft spline nuts.
Just throwing out ideas....I hope this gets resolved...
