The shop said it would "settle down" in a couple hundred miles, I'd never heard of that? It's probably not 4", but a good 2-3". Is it possible to install a strut assembly wrong to make it taller?
No, but possible to install the wrong strut assembly and change the ride height. Springs will settle a bit but not that much. I can't see an original coil spring compressing that much either. Another possibility is that the coil springs taken off were Eibach lowering coil springs.

Wobble on take off might be CV Joint, outer tie rods, inner tie rods, ball joint, sway bar end links....many possibilities. Check strut bolts under the hood to make sure they are tight. Could also be a transmission issue.
