Yeah, in the course of an instance, a resto druid playing optimally will often use almost every single ability unless no one dies so they don't need those 3 rez buttons. You should ideally be contributing some damage and not binding your balance spells will make that harder. You'll want to snag a few ticks of drinking between pulls to so may want water bound. And health stone/health pot. And your 3 combat pots.
You could macro starfire starsurge to cast when you're in moonkin form on the same button as any heals other than regrowth (since you can use that in moonkin form). Be careful you're in the form you think you are and don't pull the boss when you thought you were healing people up though.
if you can't reach more keys, smoothing casting your dots and wrath is better than healing touch.
