I would also like to hear some suggestions what kind of 3D Modeling software are the best and user-friendly.
I appreciate for the time and help! :}

For one thing, your coordinate space is distorted. From looking at the (x-z) and (x+z)/2 portions, I am led to believe that the camera angle being represented is to implement the standard 2:1 tile size ratio, which is approximated by a 30 degree camera view. ie, 30 degrees above horizontal. However, the +y portion of your y coordinate calculation doesn't take into account the foreshortening of the y axis, so objects are skewed, with y contributing too much to the final screenY coordinate. More proper would be to scale y's contribution to the screenY by sin(30) to approximate the foreshortening.
That being said, just use an orthographic perspective as 3DModelerMan suggested, and set the angle of the camera above the horizontal to be 30 degrees. The resulting render should be close enough for government work; any inaccuracy may need to be corrected with Gimp or Photoshop.
