Ditto has only one move: Transform. Both Smeargle and Mew can learn Transform as well, and they have much better stats. Metal Powder is useful because it increases the Defense of only Ditto by one stage. Leppa Berry is useful because Transform only gives Ditto 5 PP per move, and it can restore the PP of one move. Quick Claw is good because it can give a Speed advantage against the Pokémon Ditto has Transformed into.

EVs

HP and defenses.

Opinion

Ditto is not a good Pokémon in competitive play; however it becomes quite good in the Level Balance and Challenge Cup styles of play. Ditto can be used as an ineffective counter to various types of Pokémon by using their own strategy against them; the emphasis being on "ineffective". In short, Ditto is cool, but don't use it.

Counters

Anything.
