I will just answer one question.The bit about the man taking his left side away. You must be talking about CBM after the first three, maybe in the Modern Waltz. Or 456 of a Natural Spin Turn, In that case you might think he is taking the other side away. Learn what CBM is and how to use it. Just one thing about how to store energy . If you compress your knees towards your partner, it does not matter whether you are going forewards or backwards the knees compress towards each other.Dont stick your rear out. Don't let your upper body lower otherwise it will always beat your knees, and out goes your bottom The more you compress the more power you will have to use on your driving steps. Ask your teacher to explain. Good Luck
