Stuck in Gear

To put it bluntly, I've had very little luck in getting the gear I want. For those of you who don't know, I'm a rather new(bish) player who joined in around patch 2.2 in the middle of Burning Crusade. I wasn't 70 when Wrath hit, so I spent the first few weeks or so leveling Thargnik through Outlands while everyone else was racing to 80.

Well, here I am and at level 80 and continuing in pursuit for the benchmark of 1500 DPS to start running Heroics. As it stands, it seems that I'm pulling about 1250 DPS with my current gear. Now, there are still some more upgrades I can get, including a nice off-hand weapon which is a reward from Ebon Blade rep, the Unholy Persuader. This should up my DPS significantly over my currently equipped weapon, the Drakonid Arm Blade. (I was carrying around a tanking axe because of the DPS and the expertise, but switched back to this one for the time being for the stats.)

One of the things I have yet to test is the effectiveness of Magma Totem. I have been dropping Flametongue Totem in all of my instances to increase the effectiveness of everyone's stats, not just my own... but it may be that the Magma Totem is all I need to push myself over that "magic number" and convince me that I can hold my own in a Heroic dungeon.

Yeah, I know, it seems noobish to think that all this time it all came down to a simple totem switch that was holding me back. Who knows how much DPS this will actually add to my stats, as I have yet to test it.

Edit: I'm a noob.

There is also the possiblity that my measly 57 hit rating is not providing much in the way of consistency, as enhancement shamans are very dependant on their elemental damage from procs and special abilities to be a consistent factor of their overal DPS. I'm also going to be crafting myself some Dragonstompers, as the Husk Shard Sabatons just aren't doing it for me. Then there's the socket I'll be crafting on to my belt, as well as the various enchants I'm planning on placing on all of this gear (have mats!)

So what do you think? Is it just my gear? My totems? Hit rating?

Edit: So, after making some modifications, I was able to up my hit rating to about 120, and made some changes to the way I drop my totems. I ran my first heroic last night and pulled a little over 1500 DPS. (3/23)
