I'm not sure if you are going for a PvP spec or PvE.
A PVE spec that I would recommend would be

I'm not too sure on a PvP spec to use as I don't PvP much, but I would probably use something such as this:

Im wondering if i should put the points in Reincarnation and Ancestral Healing into Totemic Focus, will TF decrease the cost of Totem of Wrath?
Imp. Reinc helps some because if you ever die in the middle of a boss fight, having the extra mana when you come back lets you be able to jump right back into the fight. I'm pretty sure that TF does lower the cost of ToW, but it doesn't cost much mana anyway so it wouldn't make a huge difference if it didn't.
