For breaking glass:
i`ve seen a file just presenting a breaking shuttered glass wall in the demo section (in opspecific if using 4.0.*).
Try to modify that, i dont remember the structure but will work for you.
For the water:
some liquid simulation is also accessible, but no idea...
if needed, contact me (now, i cant reach houdini to check it up)
