I already checked for the phone number in the French version and saw no sign of it. That one was always dubious at best, though.
The running commentary actually mentioned the Betty Boop nipple flash and pointed out that it was a reference to the fact that it was taken from the original BB shorts where the animators regularly hid naughty single-frame gags like that.
As far as the altered frames, I'm using the blu-ray and French versions and reconstructing the single frames in Photoshop to replace the altered frames.
I'm about halfway through the baby herman goosing segment and I have the Betty Boop frame done.
