The amp is the 8 pin chip near the speaker pads. It's a pretty standard component. There are a number of other things that could also have been zapped, does the saber light up and everything? Reverse polarity also probably zapped the SD card.

You can send a PM to Zook, who handles repairs in the US. He would let you know how much it would cost to get repaired. However, I doubt that he could get it turned around by Halloween.

He goes by Chewbacca on Fx-Sabers. Try him there.

If you ask Erv on FX he might tell you what the replacement part is. I'm pretty sure it's a common component, but zook/chewbacca or Erv would know for sure. If it's the same as on the V3 (looks similar) it is a TPA0211DGN, which is readily available at major distributors.

If you aren't experienced in this kind of work, then repairing it yourself is not recommended. The part is very small, and their is a large heatsink pad on the bottom of the package. In order to remove it, you will almost certainly get it hot enough to loosen the nearby components.
