For the first part, see my comment to femto above.
As for the neurons changing their behavior, yes... that is exactly what I am saying. It definitely happens in the retina as the retina is reprogrammed and there is some evidence that it happens higher up as well. Though those precise studies have yet to be performed.
So, flashes of light are simply uncoordinated signaling by neurons. Turns out vision is far more complicated than the cochlear system that allows us to engineer bionic solutions for hearing. Provided the cochlea is intact, it is easy to stimulate those neurons in an appropriate manner that people can learn to interpret. Vision is another story entirely and unless you stimulate the *right* neurons with the *right* type of stimulation, its not gonna work.
