On the matter of transaction confirmation by individual miners, I found two sources which contradict your position. At http://bitcoin.stackexchange.com/questions/16607/if-a-block-chain-is-considered-invalid-how-about-transactions-in-this-block-cha?rq=1 look for the answer to the top question "If a block chain is considered invalid, how about transactions in this block chain?"  At http://bitcoin.stackexchange.com/questions/30452/how-long-does-it-take-for-a-transaction-with-0-fees-to-be-confirmed-or-rejected look for the statement "No transaction can be rejected though, there's just no such thing in the protocol."
