My toons were at the same level as yours before, here is what I am doing...
I ran the solo quests for them (solo, not boxed, the quests are easy). They give slight gear upgrades over Mastercrafted, but not really worth it. You will want the end ring the signature quest gives, so you are going to want to do the quests eventually.

The 2x access quest is in there somewhere too
Rise to Power / Temple of Ill Seen - good
Stygian Threshold - you can probably get some of the first named if you can't get them all
I had trouble with Submerged Depths at the start, you might want to wait a bit on it
You are going to want to get lots of the Queen's Coin(?) from the daily quests drop. There is a vendor selling gear which will provide some very good upgrades for you. I'm thinking of the neck/wrist/wrist groupwide CB/Pot buff items. Getting these items on all your toons will let you do a lot more zones much easier
I'd also recommend getting a crafter to the max crafting factions so you can make the green adorns.
There is a remove adornment ability now they added in, your class trainers have it.
Someone on here asked about how to improve low DPS and Cheesy made a great post on good adornment choices. There is a lot of other great info in there
