To move the entire figure, select the "body" of the figure from the drop down menu above the dials. Then you can use the translate and rotate dials. If you select the hip and have Inverse Kinematics on, the feet will be glued to the floor and the figure will get distorted as you describe. Regarding the second question: There is no simple way really... You will have to try and position the figure using the above method and look from different angles until it looks OK.
