Check out Gretchen Becker's book,
The First Year: Type 2 Diabetes: An Essential Guide for the Newly Diagnosed. She really helps to put things into perspective for someone new to diabetes.
I have also found
Blood Sugar 101 to be helpful, as well as
Dr. Bernstein's site. (Dr. Bernstein, a Type 1, advocates a very low-carb diet, which many people find helps to keep their blood sugar levels under control.)
