I feel for you bro! I had the same thing happen to me only not as much damage. And it happened while I was at work, parked IN FRONT of the bldg on the street...only feet away from the front door. They punched in my drivers door lock, breaking the handle and yanked out my stereo... Luckily thats all they took seeing how I had an ****** radar stuck on the window, blue tooth headset in the cup holder, amps under the seat and subs in the back.
I was able to get a handle and cylinder for around 180 bucks or so from a local dealership. First thing I did was get a Viper alarm.. Got that for around 200 and installed myself.
Goodluck with the rebuild!!
