After the Elite Four you can go into the Cerulean Cave, there are the strongest Pokémon in the game. I usually do this way:
1. Give EXP.SHARE to your Pokémon you want to level up.
2. Put the Pokémon to the first place.
3. Choose your strongest Pokémon, and give it Leftovers, it will restore 1/16 of your Pokémon's full HP each turn.
4. Get some potions etc in your bag.
5. Go to the Cave and when a Pokémon attacks, switch to your strongest one.
6. When you beat it, your Pokémon which holds EXP.Share will get the 3/4 of the exp. points.
Note: You can leave point 3,4 if you have real awesome Pokémon :)
Leftovers: stand there where one Snorlax was, and use Itemfinder (you must stand exactly there)
Exp share / Itemfinder: you get them from OAk's Aide.
