Clefairy cannot evolve into Clefable by leveling up in Pokemon FireRed. The only way to evolve Clefairy is by using a Moon Stone on it.
Clefairy's Egg Group is Fairy, so any Pokemon with the same Egg Group can breed with Clefairy, including Ditto, which has its own Egg Group.
You have to trade a Clefairy from Leaf Green or Fire Red.
