Need advice on handling airplane damage

Being new to airplane ownership, I would appreciate some advice from the
more seasoned guys out there. This weekend, my partner wrecked our plane.
He's okay, which is certainly the most important thing. I'm still not
certain of the details, but it sounds pretty bad. Of course I'll be calling
the insurance company today. The reason I'm writing is to gather information
on how we need to proceed from this point. I know there are required
reports, but primarily I am concerned with insurance pitfalls. I have dealt
with insurance claims and automobiles before, but I don't know if there are
any similarities or not. I do not know how to find reputable repair shops or
how to have the plane delivered to one. I don't know what point must be
reached for the plane to be totaled. In other words, I am looking for any
advice that I can so that I can make informed decisions about the situation.

Thanks in advance for your help
