Spec wise I would actually say you shouldn't be healing in 5 man content. If you are the only healer in the group, Nature's Cure is a mandatory talent. And even if you are not, you'd still want it. You have to be able to clense magic debuffs. Perhaps part of the reason you are having issues healing is because debuffs aren't being clensed that should be and people are taking significantly more damage from something that would be avoided otherwise? For example, your spec is completely unviable for Vortex Pinnacle because if anyone fails and gets Static Cling on the last boss, they will die to the one shot of his ultimate ability since there is no one to clense the debuff. Vortex Pinnacle is one of the easiest heroics, and your spec actually makes it extremely difficult. I've had a pug healer without this talent in Vortex Pinnacle and was forced to kick them simply for not specing viably. Nothing personal but if you can't do the job then there was no choice. Nature's Cure point will probably come out of either Living Seed or Nature's Bounty.
You should also have two points in Naturalist. Now there is some discussion about the viability of a no Naturalist spec however that pertains primarily to 25 man raiding context and in a situation where mana is significantly more stabilized. You however I not in 25 man raiding or at a high enough mana efficiency point to support such a spec (you should be using Nourish and Healing Touch significantly more than Regrowth). This extra point would also come out of Living Seed or Nature's Bounty talent.
You should also drop the Glyph of Innervate. In 5 man content you would never Innervate anyone other than yourself and even in a raiding situation you would still prefer to always Innervate yourself as it nets more mana. You could replace it with Glyph of Healing Touch instead. I'd also suspect if you're having mana issues it's more a matter of healing technique and spell selection rather than gear.
You currently have zero enchants. As such, that 349 item level is significantly lower in effectiveness when compared to other people in 349 item level. You can't neglect your enchants. Enchanting alone adds about half a tier in value to your items so that 349 enchanted actually looks more like 356 unenchanted. You could also have a belt buckle as well improving your gear. You should not be neglecting this.
You not benefiting from the profession bonus of your crafting profession, inscription. You need to level that more for your cheap shoulder enchants. Professions are buffs as well.
Despite all of that, you probably could heal the troll instances fine with the exception being Nature's Cure. You will require this. However will people live is another story because that will actually come down to your familarity with the content, when to heal who and with what abilities. When does heavy party damage shift into heavy tank damage? When can you hold off on healing someone until later. These are things you will learn through experience.
