gems...full int for pve, either full resil or a mix of 10int/10resi gems for pvp
for prime glyphs: id def take swiftmend. then either pick between rejuv or lifebloom, with regrowth as a possibility as well. prioritize whichever will boost your healing style the most (so prolly not regrowth)
for major: barkskin as one, and either innervate if you play with a mana based class that you toss innervates on, or HT if you dont
for minor: dash for sure. then pick motw if people are dispelling that and you find you have time/gcds to use recasting it...if you dont encounter people dispelling motw or dont have time to recast it ever then just pick treant. rebirth if this is a BG/pve spec too i guess, but afaik rebirth cant be used in arena so thats why i left if out as a major and minor choice - assuming this is aimed at arena.
