Here are a few references I found about the role of calcium in insulin resistance:
http://npgibson.com/classes/diabetes...ts/Calcium.htm
Calcium may play a role in insulin secretion, and may correct reactive hypoglycemia. Diabetics may deposit more calcium in arterial walls. This would be a secondary mechanism by which diabetes contributes to hypertension and atherosclerosis. Diabetics may have an increased chance of osteoporosis, so it is a good idea to take a calcium supplement. This is also another good reason to exercise.
Forms
Calcium is not well absorbed into the body, and the form is very important. Calcium is absorbed best when it is chelated (attached to something easy to absorb) in various forms, such as citrate, malate, amino acids, or glucose. Calcium carbonate is not well absorbed.
Dosage
Diabetics should take the usual recommended dosage, 500-1500mg daily.

To prevent osteoporosis we are told to take calcium. Yet when you are insulin resistant the bones do not absorb the calcium since your body now has trouble building new healthy tissues. Excess calcium can end up in the arteries causing plaque build-up.

A research review concluded that nutrients found in dairy, including calcium, may contribute to the reduction of body weight, body fat and insulin resistance syndrome. Teegarden D, et al. Symposium: Dairy product components and weight regulation. Journal of Nutrition. 2003; 133:243S-
Among overweight young adults, higher dairy consumption may protect against the development of obesity and insulin resistance syndrome and may reduce the risk of type-2 diabetes and cardiovascular disease. Obesity is one of the risk factors of insulin resistance syndrome. Periera MA, et al. Dairy consumption, obesity, and the insulin resistance syndrome in young adults: The CARDIA Study
