Hi,

1.  Just set EdgeForm[] in the ContourStyle option
2.  you must generate a 3d interpolation and make a 
    ContourPlot3D[] on the interpolation

You may look at

http://phong.informatik.uni-leipzig.de/~kuska/mathgl3dv3

the OpenGL Viewer has now a buil-in iso-surface command
with interactive adjustment of the level. Clearly
MathGL3d is much faster computing 3d contour surfaces,
50000 polygons/second can be found and rendered with
MathGL3d. It has an automatic polygon reduction that
will also create nice triangulations for fine resolved
data and functions.

Regards
  Jens
