If you just want to heal and don't care about hit capping, I say go arctic buckler with 10stam/10spirit (it's a newer chant) then use the pvp ring. That will add a nice amount of spirit and armor. Keep it mind holy spec gets meditation with alows 50% of mana regen from spirit to continue in combat, someting like that. With that, you can continue to use spirit and gun for the elder dungeon cape, if not that then use the haste one. Id go with +5resist all as cape chant, and arctic adds 5frost resist so 10 total is cool. Arctic is greater then forest imo, the armor difference is mass, you can make up the stats with some leather/cloth gear in other slots.
