About the curved lines...  I had the same problem with my first ray-tracer.
May problem was that I had the viewplane too close to the eye-point.  Think
about it: you're not shooting rays through equispaced points on a SPHERE, but
a PLANE.  Just move the eye away from the viewplane a bit, and increase the
size of the viewplane.  Hope this helps!
