There are just the 2 lever arms. How come you want to replace the levers? If it ain't broke don't fix it....
As for the ball joint ends, when I replaced mine (i had the red ones before on my 99'), I put a little bit of general purpose synthetic grease on them. I don't know what the official word from Porsche is though.
Maybe some of these pics will give you and idea of what's involved:

Make sure you line everything back up when you reassemble.
Good Luck,
