If they have mostly bloomed, you can move them to the low temp refrigerator. Not sure why you have black mold,
As for wrapping them, I find that in some cases it does really good things for the cheese and in others it can cause the PC to recede and the Geo to take over, or worst, it can cause a skin slip or fast outside maturation before the inside is ripe. I used to blame myself for the errors until I found that some wrapping materials work incredibly well and some are "professional" yet bring abut poor results.
Since you have quite a few wheels there, I would suggest to test it out and see which works better for you by only wrapping half of the wheels. This way you can compare the development speed and quality and see if the rind looks different when wrapped or not. Better than having a mistake and having to throw all the cheese away...
