yes you can
yes
Spheres in Pokemon diamond are found underground. Go underground using the explorer kit, touch the touch screen and look at the some shinning things(this means there is a sphere or treasure), if you're near the shinning things, touch the touch screen and you will see were they are located (they are still shinning things but you can see them in the touch screen), then go in front of them then press A.
No, you will need to trade it as soon as its on pokémon diamond
no
i think a dude gives to you when it is still a little egg.
You Can't I'm afraid, you can only get a shieldon in Pearl by digging in the underground to find the fossils. Cranidos is a Diamond only Pokémon you will have to trade it through the Global Trading Station or get it from a friend. But you can still find all the previous fossils from the previous versions in the Sinnoh Underground
NO FREAK ITS A KIDS GAME i play it but STILL!
No, it does not, because I copied my Pokemon from my Pearl version and my Pokemon were still there when I played it.
