Bungalow, Knee Wall Insulation and Venting

I, as many others have scoured these forums for days reading everything I can regarding my new house and its stupid knee wall attics. I have a 1947 built Bungalow which is a pain with its ice dams and its poorly controlled heating/cooling upstairs. The house has two vents per side that are on the roof. They are not gable vents. They are directly on the roof. There are no soffit or soffit vents. I have attached a picture of the backside of the vent after I ripped some insulation down. Currently there is insulation in the form of faced fiberglass batts on the rafters, knee wall and limited cellulose blown onto the floor of the attic space. The first question is, without soffit vents and living in detroit (zone 5), is there any way to insulate the sloped rafter side, thereby putting the attic "inside the conditioned space" without creating an environment that is prone to mold/condensation?
