You get through victory road and then challenge the elite four. After that, your objective is to catch all Pokemon in the world.
Pokemon badges in leaf green is a proved sign that you beat a gym. And it makes it so you can battle the elite four or people so call it The Pokemon league and beat the game.
Sadly no, but their is the soul silver or heart gold game, once you beat the elite four you can travel to the kanto region, and get all eight of the kanto badges. So you can get the leaf green badges too.

you need to catch it first in fire red/ leaf green and migrate it to pearl after you beat the Pokemon league.
