I can't tell from the front measurement whether the alignment is within spec. From the "pulling" its either an incorrect alignment OR a bad new tire. Try rotating the tires front to back and see if that changes anything. New out-of-spec tires are quite common.

He doesn't have any MB experience if he had to ask if it had a steering gear box. I'd find another alignment shop. Perhaps call around to the higher end body shops and find out who aligns the more critical repair jobs (Lexus, BMW, Porsche or MB's).
