Do you soak one or both sides of the stone?

I can't definitely say that soaking damages the 6000 side, but my 6000 side is starting to disintegrate after less than a dozen uses, and I've been soaking the whole stone (including the 6000) side.

What holds the stone to the base while sharpening so the stone doesnt move?

Basically the water creates suction with the water in the base and holds the stone. Along with the ridge on the base you wont be losing the stone any time soon. Even if you didn't have the base the friction from the stone on most surfaces will keep it stationary.

Is this also made to sharpen ceramic knives made from zirconium oxide?

Really, I would use diamond stones - they aren't that expensive and are much harder than zirconium oxide. A ceramic knife is a knife designed with a ceramic blade typically made from zirconium dioxide (ZrO2; also known as zirconia). These knife blades are usually produced through the dry-pressing and firing of powdered zirconia using solid-state sintering. It is 8.5 on the Mohs scale of mineral hardness, compared to 4.5 for normal steel and 7.5 to 8 for hardened steel and 10 for diamond. Aluminum oxide grit stones (like this) are 9 on the Mohs scale (not much harder). Silicon carbide stones are 9-10 and would hold up better. Diamond is best, but you need a quite fine grit to sharpen the edge to a cutting edge.

what material is the stone made from?

The stone is man-made and is made mostly of ceramic.
