I'm sorry to say but no you cannot trade Pokemon from soul silver to sapphire because they are not made in the same format thus you cannot trade. But you can migrate them. Which means that you can move Pokemons from sapphire to soul silver but cant move it back to sapphire again. And you cannot bring soul silver Pokemon to sapphire.
no you can not crystal version is too old try trading Pokemon to it with fire red,
leaf green, Or Diamond, Pearl, Or Platinum
Not at all, actually, technically or otherwise. They are two generations appart, on different systems. Things exist in Ss that didnt in Emerald.
no you can't but you can migrate in into diamond and then trade it.

Yes
you need to trade it for it to evolve
No, you don't need the National Dex to evolve Haunter in Pokemon SoulSilver. You just need to trade it with a friend then trade it back. Then, you have a Gengar!
there is no possible way until heartgold and soulsilver come out on march 14, 2010. then trade it to platinum.
Sadly you can't as you can catch rare Pokemon fairly easily on Pokemon ranger and it would be cheating especially with those rare legendaries. Although you can trade heartgold, soulsilver, pearl, and diamond with platinum. You can also trade Pokemon from earlier generation games using your internet.
