1) Picking the die is allowed (always, not just when using this card), using the mana, however, is not.
Using a die from the source is only allowed if you immediately use the mana that it generates. See "Using Mana", section 3(b).
However, the stronger effect of Mana Draw is not using a mana die, you take a mana die and set it to a color and generate mana tokens. So you can do that even if you don't use the tokens immediately (or ever).
