The Lost Dwarves are three elites, Baelog, Olaf and Eric "The Swift", and they fight as one encounter. Plan the pull for all three. They're humanoids, so crowd-control one if your group can, and kill the others one at a time. Each dwarf's own drops are on his card.
The Lost Dwarves asks Alliance players to find Baelog in Uldaman.
TankHold every dwarf that isn't crowd-controlled, and keep them together so the group's damage lands where you want it.
HealerThree elites spread damage around. Watch the whole group, not just the tank.
DamageBurn one dwarf at a time, and never break the crowd control on the others.
