How Would This Procedure Be Performed? Transfer to Offline wallet
I need to do is a "transaction" from my online wallet to a newly created 'offline' bitcoin address? In 10 years, in order to access these coins, I ONLY need that new bitcoin address and its private key?


Yes.

You can use Blockchain's product or print off an single address page from http://Bitaddress.org. Send a transaction to the public key and safely store that piece of paper until you next need it. Be very careful, though, because if you lose that piece of paper, you will lose the coins associated with that address.
