Is this the drain plug for the front differential?

That's cozmalene{spelling?}, an anti corrosive or anti oxidizing material applied before shipping. Every Porsche comes from the factory with it. Some people remove it and some don't.

Yes that is the drain, and the fill is to the forward and upper left. If I remember correctly, it's a 17mm.
The front diff will take approx 1.8 quarts when drained completely and the tranny will take a bit more than 3.5 quarts. Just get the car level and fill until the fluid starts dripping out of the fill hole.
