Guildmaster Grovyle:"Why do the ponies need Queen Novo's pearl when Twilight Sparkle has transformed ponies into other creatures multiple times before?"

Maybe they needed something powerful enough to counteract stone grenades and simple transfiguration spell wasn't enough.

Also, Celestia could be thinking not about a Perl, but the fact that hyppogriffs had encountered Storm King. Maybe she wanted Luna to learn more about him before counterattack.

Guildmaster Grovyle:"if the Storm King's staff was believed to be capable of fixing Tempest's horn, why did the ponies not try using it for that end?"

That's the thing - it wasn't! He just promised Tempest to fix her horn and she wanted it so much that she didn't even think that he was just lying.
