You don't need to defeat the elite four twice. Only do it if you want to!

heartgold and soulsilver before and after elite four and other ds ones after elite four
To get the second Elite Four, you must have already defeated the Elite Four the first time, and the second time you go to fight them, they will all be leveled up, and become the 'Second Elite Four'.
after you beat the elite four, it will be on route 25.
Go to mt.silver after you beat the elite four

The Elite Four is actually comprised of five people. There are the first actual Elite Four, and then their champion. They are Will, Koga, Bruno, Karen, and Champion Lance.
You can go to Kanto and beat the Gym Leaders and Elite Four there. You can also get Kanto and Hoen starter Pokemon.
