"I think I remember reading somewhere a while back to set a ruler straight down from the water dropper and focus on it?"
Or you can drop a string as well to get your focus. The 85mm Macro will work fine, you just need to have the lens a little closer to the water. Getting that close may make the use of a tripod a bit tricky.
I'd play with the informal setup first and then look at purchasing the kit if you want to seriously pursue water drop photography.

I've seen videos where they put a "ratchet extension" or any object that can stand upright on it's own in the middle of the container of water. However, the object must extend up high enough out of the water and be centered underneath the water drop so that the drop hits the top of the object every time. That is what you focus on ... Hope this helps.
