I wouldn't bother with improved weapon totem. The DPS gain is minimal and you lose a fairly significant amount of utility. Just go full resto and the rest in enhance with improved guardian totems and instant ghost wolf. Mana is more based on gear and smart use of downranking than which talents you choose. Even as full enhance you can heal dungeons fine as long as you have decent resto gear.

Also wouldn't bother with totem twisting. Huge headache for minimal gain and it nukes your mana pretty hard.
