Hi and welcome aboard Hope you get to show some of your work soon.
1: No, as far as I know the mousewheel is not supported.
2: That is not how it should work. I had the same problem you describe when I was using two different Wacom tablets, one at work and one at home. I figured out that I needed to uninstall/reinstall the wacom drivers everytime I switched tablets. The problem, AFAIK, lies with the wacom drivers not Zbrush as it also caused trouble with Photoshop(full opacity) and Alias SketchBook(also full opacity on strokes).
For me the problem solved itself when I changed to using just the one tablet on my laptop.
1. Is zooming in and out of an image with the mousewheel supported? Or is there a way to customize this if not?
Currently it is not supported. I do not know if this could be accomodated through the use of ZScripts or not. It would certainly be a cool feature!
Whenn I am drawing a 3d sphere, I drag diagonally but I'm not seeing a preview of what I am drawing, I then complete the diagonal stroke and the sphere pops up. Is that correct? Seems like there would be some kind of preview like when one draws in any 3d program or Photoshop or Painter?
Can you elabortate more on this? You should indeed see the sphere being drawn out on the canvas. I am not sure what is going on here. Some more info would be helpful.

I uninstalled and reinstalled the wacom drivers. Now I see the updates fine.
Thanks for the quick responses, guys.
