It looks as thought my diagnosis back in December 2009 is/was exactly as yours and I had chemo, radiation, lumpectomy, Herception, the whole ball of wax and I was also Grade 3 and also had some "DCIS" in there as well and no spread to my lymph nodes. By now you've already begun treatment and I hope you are doing well! Sorry to hear of your diagnosis. Be strong, you can get through this, I did!
My checkup is tomorrow with bilateral MRI of the breasts and then thur checkup with bloodwork and results of MRI with oncologist. GOOD LUCK!
