I want to add "rising and lowering" capabilities to my camera class. In order to do this, should I get the cross product of the (view - position)vector and the strafe vector and just times the result by a scalar or just mulitply the up vector by a scalar and add the result to the view and positions ''y'' component?

Is your camera looking at the origin, or at some other object? If you''re looking at an object not located at the origin, you''re going to want to translate the camera along a vector that is a scalar multiple of the up vector. Be aware that if you want to still be looking at the same object after the upward or downward motion, you will also have to rotate the camera.
