I personally think that the wheezing and the aggressive behavior was just a part of the shedding process. My girls are moody when they shed too. On the other hand, my boys could care less.

Observe her and see if she continues with the wheezing and the yawning. I'd also recommend letting her adjust a week to her new home without you handling her. After a big move she might be insecure in her new environment and needs time to adjust.
