To be honest, as long as your tank has the def. rating you could multbox heroics in green. My first 80 was a solo character and I did heroics in green gear with him. In a number of occasions I did more dps than those geared for heroics.
I'd just take the team in there and get some heroics done and some regular ToC as well and that will get you some raid gear due to the emblems we get now. Also ToC drops naxx level stuff so you can get some really good upgrades just farming that.
