Shad in general you are correct, though with the arrival of the RAF program, the locals who have been multi-boxing for a long time have been swamped with people asking questions that have already been answered dozens of times. I was guilty of it a little myself, doing searching and reading the wiki here and the FAQ on RAF at the official site will help a ton.
If you go into the account management of your main account and hit the RAF tab and email yourself to invite yourself, you get an email with an activation key for a trial linked to your main. You then set up an account using that key, then (likely) activate vanilla wow and TBC. At that point if you have toons from the main account and new acount grouped together they get the bonus if they are equal level and below level 60. The new account generates one gift level for each 2 levels they gain , starting with the first one at L3. The gift levels can be given to any toon on the main account that is below the level of the gifter. You're not supposed to be able to gift a toon to above 60, but apparently it may be possible for now.
There are other bonuses associated with the link (summoning, rare mount), and the link is active for 90 days.
