You do not 'unlock' anything in Warcraft III story related. They come naturally as you continue through the game.
However, I am sorry to inform you that if you do not own the expansion to Warcraft III: Rain of Chaos, you cannot play the Human campaign with Arthas found in Warcraft III: The Frozen Throne.
You can purchase The Frozen Throne at a local store in the popular 'Battle Chest' box, or order it online.
No, you only have the ones available.

There is no world of warcraft 3. There is world of warcraft, and warcraft 3. Unless you want to refer to Cataclysm. If so then no, you'd fail.
No, as Cataclysm is meant for World of Warcraft, not Warcraft 3.
