You have a few pieces that should be replaced, like your helm, neck and the Band of the Victor. They're ALL easily replaced from questing. Take a look at the Pre-Raid gear list that's stickied at the top. You're also missing a lot of enchants. Your boots, your back, and your weapons don't have any enchants. You'd also get a lot more out of +6 stats to your chestpiece. If you're waiting to replace them, just take into consideration how long it might take, and enchant accordingly.
A lot of people will tell you that Heroics can be just as hard, if not harder than Kara- especially if you do PUGs. Don't go into Heroics thinking that you won't notice the change in difficulty. I've seen people get turned down because of their gear, and I've also seen people in epics get kicked out of a heroic group because they weren't performing. BM isn't too gear-dependant, but having sub-par gear means you have to know you're doing to pull your weight.
