After you catch Mewtwo, you have finished the main points of the game, but it may be impossible to completely beat a Pokemon game. After I caught Mewtwo I just trained my Pokemon and looked for new ones. You can also try to beat the Pokemon League again, or try to beat your record at Trainer Tower.
As of the current data for Ash catching Mewtwo the answer is no. Right now nobody has captured Mewtwo due to the fact that he is such a strong pokemon.
