    When you are bending a leg for example, the knee will point towards the Hint's position.
    You need the Hint's position in RootSpace to implement it correctly.

    I am not sure what you mean by this question. But, if you mean to control the foot's rotation in a leg IK, you can fully control it if it is specified as the Tip of the TwoBoneIKNode.SetupMessage. The Tip will use the Target's Rotation and Translation plus any offsets if specified in the TwoBoneIKNode.SetupMessage as well.
