I'm guessing these stats are for your Mage, Kodama? The most common Mage DPS build, at the moment, if the 36/30 pyrolock; it's a lot of dot management, though, and a 51 pyro/5 archon/ whatever might work out better for you. In either case, bluedots.org has a whole bunch of Mage resources you might find useful- theory crafting, builds, etc.
Statwise, your 190 focus puts you firmly in the Expert Dungeon branch of instances. You might be able to rune up to the 220 focus most leaders require for T1 raids (GSB, RoS, GP, DH) but at the moment, you're still a little spell power light- I'd recommend 1100-1200 SP before you do anything other than archon, but that's a very specialized position.
When you say your DPS is low... it could be gear, rotation, or spec. Rotation's pretty easy to fix, but takes some time on the dummies; spec requires learning the new abilities AND rotation. If you're running a parser, even a quick-and-dirty one like Simple Meter, it'll give you an idea how you do. I wasn't pushing over 1k until I got all the way through DH and GP a few times. I still parse relatively low for my gear, but that goes back to build and rotation.
As far as gear goes... Have you looked at the Marketplace section on the site, here? You'd have to participate for a bit before you could actually submit an order, but vault credits stack up fast, and you could order yourself some crafted gear.
tl;dr: Mess with your builds some, find something that's fun for you to play and does decent DPS, and keep doing experts- you'll get there.
