Triumphs

Has everybody completed the triumphs? I just noticed it. I haven't played Destiny since before HoW dropped. I have one month to find two more gold chests, defeat Crota on Hard, Capture Skolas in the Citadel and defeat the prison of elders on hard. Do you think its doable in a month? I need to get my light level up too. My highest light level is my Titan at Light Level 32. And my best weapons have 331 attack. I'm a Day 1 player and I want to complete these Triumphs for the exclusive Year 1 emblem.
