in response to number 3 the reason the other things don't shatter when the crystal heart does is that they are grounded so the vibration just passes through them into the earth. the heart isn't grounded it is suspended and spinning therefore it was vulnerable to being shattered by the sonic cry of flurry heart which i believe is her royal canterlot voice, a manifestation of her earth pony magic. perhaps celestia's and luna's cries when they were first born were like that too.
