well, i don't know much about power booleans or procutter, but here's a spectacular fracturing/shattering tutorial by Tyson.

there's plenty of glass-smashing tutorials out there, just do a google search. Check out Allan McKay's website.
As for using the procutter to cut up your geometry, though, maybe someone else can help out.
