Assuming you have 12 hours advance notice:
Box up the filing cabinet and save those records. All photo albums and negatives. Family videotapes. The external hard drive with all the digital pictures. Kids' artwork. The address book. Wall calendar. Sentimental value items that are easy to carry. High value items that are small and easy to carry. Clothes, and toiletries.
Then walk around with the digital camera and take pictures of the crap left behind for insurance purposes.
I'd be very torn when it comes to my work shop. I'd probably fill a couple boxes with heavy hand tools. Leave the big stuff to burn. We have a small car though, so most of the tools would burn.
I'm probably missing some important stuff there.
