You have to make the following Pokemon hold the metal cloak and then trade them: Onix = Steelix Scyther = Scizor
No. Scizor can't use the stone edge move in Pokemon.
no there isn't. no trainers have scizor, dusknoir, electivire, magmortar or rhyperion. unless you use find a partner in the battle tower that might have one then no. parnters in the battle tower often use very rare Pokemon but the Pokemon you see in the fights are not recorded on to the pokedex.

You cannot find it in Diamond; the only way to get a Scizor is to give a Syther a Steel Coat, trade it to another person, then trade it bak again. It should be able to evolve into Sizor.

Scizor is a Steel and Bug type pokemon.
Evolve from Scyther by trading it to another player while its holding a Metal Coat.
You can't cath a Scizor in Pokémon Pearl. You have to trade it with Pokémon Diamond, Platinum, HeartGold or Soulsilver. You can also migrate it from Pokémon FireRed or Pokémon XD
You can't get scizor on Pokemon leaf green. However, you can trade if you have Pokemon fire red.
you can't get scizor and not even syther in Pokemon sapphire, only by trading
The Pokemon exclusive to Pokemon Diamond are: Seel, Dewgong, Scyther, Scizor, Murkrow, Honchkrow, Larvitar, Pupitar, Tyranitar, Poochyena, Mightyena, Aron, Lairon, Aggron, Kecleon, Cranidos, Rampardos, Stunky, Skuntank, and Dialga.
Your team sounds mostly good to go. Personally I would switch out Pikachu and Rapidash for something like, say, Scizor and Aerodactyl, but the team you have right there sounds good to beat the elite four. Just make sure you are high enough level.
