All the moves that #281 Kirlia can learn in Generation 4 (Diamond, Pearl, Platinum, HeartGold, SoulSilver), plus for its egg moves, compatible parents and breeding details.
Well, I hate to break it to you, but Kirlia learns none of those moves. It learns them all as a Gallade. Brick Break is a TM move, Night Slash and Leaf Blade are learned by going to the move tutor in Pastoria City with a Heart Scale, and it learns Psycho Cut at Level 31. I suppose you should use the stone around that level.
