Keep slogging through the main scenario quests, you need to finish everything up to and including 2.55 to access Heavensward when it comes out. Also, start working on the Hildibrand Manderville quests at the same time. Between the two quest chains that should complete all the dungeons you need to unlock Expert and Trials Roulette. Do every single dungeon once for the first-time bonus and to unlock High Level Roulette.

Gear-wise, I'm not sure if you unlocked Crystal Tower (CT) yet - it starts from one of the quests you pick up in Revenant's Toll - but once you complete all three CT raids (Labyrinth of the Ancients, Syrcus Tower and World of Darkness) it unlocks a weekly quests which rewards the Poetics item upgrades and the item for buying the weapon. Three weeks of hitting your poetics cap, pick the tomestone one week and the carbontwine another from the weekly, and you can get your hands on a 130 ilvl weapon, which is better than anything else you're likely to get short of upgrading your relic all the way to its final stage (which would probably take a couple of months at least).

Basically your progression should probably be getting whatever left-side drops you can get from the three CT raids, moving up to the next as soon as you hit the necessary ilvl requirement. Save your soldiery for a weapon first (1300 solidery + a tomestone dropped in ST for 100 ilvl, upgrade to 110 using Sands of Time also from ST) and then accessories, and keep saving your poetics towards the 130 weapon. There's no loot lockout on any of the CT raids, so you can do them as many times as you care to, and if you have good luck with RNG you can get really geared really fast.
