You need the pokeradar after you get the national pokedex then go to the patch of grass near twinleaf town or eterna city.
I found a shining stone on my way out of the caves on iron island. No work required to get it really.
You can find Pidey in a Pokemon Outbreak in Pokemon Diamond

You can not find or get manaphy on Pokemon diamond but you can by hacking, trading or... if you have Pokemon ranger you have to complete the manaphy mission and then you can put it onto diamond.
It's very hard to find a shiny Pokemon but if you use the PokeRadar and go to the shining patch of grass (if there is a shiny patch) you just might find one but don't get your hopes up 'cause I tried that many times and I never got a shiny Pokemon.
You can't find a Ho-ho in Pokemon Diamond. You have to migrate.
To get a Manaphy in Pokemon Diamond you have to get Pokemon ranger and defeat it and you have to trade it to Pokemon Diamond,Platinum or Pearl.
its not a Pokemon
Not really that rare... in Pokemon Diamond you can find Sunkerns on Route 204
you have to catch all of the pokemon in diamond or SEE all of the pokemon
you can find legendary Pokemon by using your Pokemon tracker
