The first one seems to be fine if you are not seeing any excess mucus in the mouth or bubbles.
Sometimes when you open up a snake's mouth, small saliva bubbles will be located at the throat area. If the saliva seems stringy and the snake has larger bubbles around the mouth and tracea I would set up a vet appointment.
The wheezing could just be from the stress on the snakes moving into a different environment from what they're used to. I would keep a close eye on the second Ball and raise up the temps a couple degrees. If you can try, see if there's any bubbles within the tracea when the snake opens it to breathe or in/around the Jacobson's organ and nasal cavities at the top of the mouth.
Also if you have a good camera pics of the mouth would be helpful.
