Damn, that sucks, but it can be saved!
Take it to the LBS and get the threads chased. You might be able to save it.
if they're totally dead, try to track down a Mavic Bottom bracket. They're hard to find though.
They've got cups with flanges on both sides that thread onto the BB, not into the BB shell. So they're perfect for stripped shells.
