It looks to me as if the only one of your questions which wasn't answered is the one regarding military suspension, however you did not really give enough information to provide an answer for that question.
When asked if your brother was serving in the US military, you responded with "Korea". Does that mean he is serving in the US military in Korea or is he serving in the Korean military??? As far as I know, Verizon only will provide military suspension for US military personell. Deployment orders would have to be provided to Verizon in order to receive the suspension/cancellation.
Additionally, when transferring authority to your brother via AOL, a deposit MAY be required depending on his credit history.
