The only real dangerous thing is when he does his whirlwind move. He'll scream, "Blades of Light!". You then have about half a second to move away from him, about from the middle of the room to the stair. If you have a melee pet or minion, make sure to get it out of the way as well. Make sure the tank gets Herod focused on him, or your healer will probably get owned with a few swings of his Ravager axe.
I believe Herod is immune to magic spells while he is spinning in whirlwind, but not immune to normal ranged attacks. (As a hunter, I was able to shoot him with auto-shoot but my Arcane Shot always fails.)
After he dies, around 20 or so Scarlet Trainees come in and rush to attack. Just use any AoE spell (Explosive trap the entrance of the room when Herod is almost dead), and they die within seconds. They have a really, really small chance to drop the Scarlet Tabard, which is a cool tabard that is red in color.
