We examine the depinning transitions and the temperature versus driving force phase diagram for magnetically interacting pancake vortices in layered superconductors. For strong disorder the initial depinning is plastic followed by a sharp hysteretic transition to a three-dimensional ordered state for increasing driving force. Our results are in good agreement with theoretical predictions for driven anisotropic charge-density wave systems. We also show that a temperature induced peak effect in the critical current occurs due to the onset of plasticity between the layers.
