You're probably just about ok for some of the early heroics, but you have a bit to go still until you are ready for the later heroics and 10 mans.
For an indication of what level you are at gear wise take a look at: http://www.tankspot.com/forums/warri...-minimums.html
You have some upgrades available pre-heroic atm that you might want to consider, eg.
[item]Strength of the Untamed[/item] From CE Rep
[item]Flesh Beast's Metal Greaves[/item] From MT quest
[item]Wind Trader's Band[/item] Netherstom quest
[item]Protector's Mark of the Redemption[/item] SMV quest
For a more complete list take a look at: http://www.tankspot.com/forums/gear-...gear-list.html
You might want to have a think about your gems and enchants too.
I reckon if you sort those last few bits out you will be set for most heroics and perhaps Kara too
