signrawtransaction - Which private key from BitAddress.org?
Ok.....

Since nobody answered. After smashing my head against the wall for a day, I finally figured out that since I am developing right now, and I am using testnet, the private keys generated for testnet and the private keys generated for "real net" are not interchangeable. So I had to switch BitAddress over to testnet mode to get keys that would work for my transaction.
