1. what cammera settings will give rendering in with coordinates of each 
point (x,y) are representing angles beetwen camera, i.e. in 360x180 image :

sphere { z*100 } 
  then rotaten horizonaly by X degrees will be in image on (180+X,90)
  then rotaten verticaly  by Y degrees will be in image on (180,90+Y/2)

<0,0,100> (in front of camera) will land in center of image (180,90)
<-100,0,0> will land in (  0,90)
<+100,0,0> will land in (360,90)

so general 
sphere { z*100 1 rotate x*X rotate y*Y }
will be in image in (180+X, 90+Y)

camera {
  // what put here ?
  location 0
  look_at z
}

I'm not sure I understand your question but perhaps you are asking about
spherical camera...
