If you have the GOTY edition, then all the free DLC's are already in the game.
For the alternate looks
From the startup screen, go to options, then gameplay.
You won't see them until you scroll down.
There is a slider on the right, or you can put your mouse over one of the visible options and use your scroll wheel.
