Badge grinding on 5 Shaman

So I've been lurking and reading the forums for a couple months. I've been a 2-boxer since shortly after release loving the lock/pally combo of uninterruptable hellfire farming and after reading the boards here decided to start leveling 5 shaman in December. I hit 70 earlier this month and have been grinding rep to be ready for the free blue pvp gear coming out in 2.4.

I was just wondering where a mostly quested blues geared group of shammies can farm badges easily. I'm setting up kara runs with guildies to hopefully clear weekly (hopped into a pug killing prince last Monday and it was hilarious), but figure I'd also start giving some heroics a shot. Being pretty undergeared I'm sure it'll be tough, but wanted any pointers anyone can offer on the easier instances to get to a boss or 2 in for farming while I gear up. If you're interested my shammies are Xibitz, Xibita, Xibitb, Xibitc, and Xibitd on Whisperwind (where my other 8 70's are). Thanks for any help!
