I sent this in an email to Jim as well, but I recovered what I thought to be the wallet (multibit.wallet, and a bunch of other ".wallet" files). I couldn't import multibit.wallet (see the following error):

 Could not load the wallet file the error message was "com.google.protobuf.InvalidProtocolBufferException While parsing a protocol message, the input ended unexpectedly in the middle of a field. This could mean either than the input has been truncated or that an embedded message misreported its own length."

So I tried adding one of the other wallets, and the balance showed up successfully. For some reason, though, I can't send money OUT of the wallet, thinking that I'm somehow just seeing the public information and do not have full access. I'm at work now, so I can't try anything further until I get home, but I hope I can sort it out.
