So here's the latest.  bitcoind getinfo shows a balance of 0.44858058
Adding up the amounts of the listunspent outputs is 0.40257368
The discrepancy is 0.0460069
I just did a sendtoaddress for the sum of the unspent outputs (0.40257368), and everything worked.

Here is my current output:
$ bitcoind getinfo
{
    "version" : 80600,
    "protocolversion" : 70001,
    "walletversion" : 60000,
    "balance" : 0.04610690,
    "blocks" : 299627,

}
$ bitcoind listunspent

        "confirmations" : 13069
    }
]

Thank you SO much for the help.  I'm a happy camper now that I at least have the funds out of the wallet.  I wish I knew what caused it, or why there is still a discrepancy between the unspent outputs and the balance.
