thanks that answeres all questions wasnt sure if draw step was included as a part of the upkeep, I had been told that you can float mana through your upkeep to use during your draw step because it is all the same phase, does this work as well ?
Yes. If you add mana to your pool in your upkeep you can use it in your Draw Step.
This is because they are both part of the Beginning Phase of your turn. You can float mana through steps in a phase, just not to the next phase.
