Muatvault

If I have my Mutavault, and I animate it, can I immediately attack with it, or do I have to have something that makes my creatures have haste, like Purphorous or Blur Sliver?

Once it is turned into a creature, it IS affected by Summoning Suckness, so yes, it would need haste

Yes and no. Once {mutavault} is a creature, it obeys the same rules as creatures in that it needs to have been under your control since the beginning of the turn to attack or tap to activate abilities. If you have had it under your control since your most recent turn began, you can attack without it needing haste.

302.6.: A creature's activated ability with the tap symbol or the untap symbol in its activation cost can't be activated unless the creature has been under its controller's control continuously since his or her most recent turn began. A creature can't attack unless it has been under its controller's control continuously since his or her most recent turn began. This rule is informally called the "summoning sickness" rule.
