Okay so some advice on your current gear:
Your weapon is somewhat low on the item level side, so you might want to replace it with either
Runeblade of Demonstrable Power from the Ebon Blade reputation vendor or, preferably,
Orca-Hunter's Harpoon from Halls of Reflection Heroic.
Also, you have a Spellpower trinket still, which would ideally be replaced by one of the following:
Banner of Victory - Trial of the Champions Normal
Mirror of Truth which you can get with 40 Emblems of Heroism (you can get EoHs by downgrading Emblem of Triumph a couple of times).
Incisor Fragment from King Dred in Drak'tharon Keep Heroic
Meteorite Whetstone from King Ymiron in Utgarde Pinnacle Heroic
In fact, all four are better than both your current trinkets, so if you get any 2 of them you can replace your other one as well.
Now, the important part about getting into raiding: Gems and Enchants (you can't get into raids without them!
I would suggest to consult this guide:

If you feel like they are too expensive, most Enchants and Gems have cheaper, discounted versions so you can also use those for the time being.
But yeah, if your country has a Local forum listed here:
