It is best to ask your broker that question or check out their website. Normally, brokers will only wire funds to bank accounts in the account holder's name.
No, typically you have to have the wire instructions in place and signed by you. Some require your signature to be notarized. More recently, some brokers require a test transaction of a few cents in and out and then verified by you before approving it. You could call the brokerage and find out what wiring instructions are in place and for what bank.
