To get to Holiday Hi-Jynx, you need to do the Porygon episode first. Once it's completed, Jynx should appear on the little sandy part near Duplica's mansion.
To do Go West Young Meowth, you need to increase one of your Pokemon's toughness, smartness, and coolness by giving the appropriate shard to one of the condition upgraders located in 5 of the towns in the game (I think they're in Pewter, Vermilion and Saffron). Then go talk to the director again and he'll film using that Pokemon. Go to Celadon afterwards and go to the Hollywood Blvd. theatre to trigger the event.
Lastly, to get the Bad to the Bone event to activate, you must return to Pallet after the Pokemopolis event and speak to Oak. He will tell you that the Pokemon League is starting. Head back to Route 22 and you should trigger the event.
