The sun appearing in all positions along the equator is a quantum physics effect.  Basically, the sun exists in such a state that it hasn't determined it's starting position, and thus exists in all posible starting positions along the equator.  It's momentum keeps it moving, so it effectively shifts position along the equator.  The sun is not a big entity, being close enough to the plane provide its warmth.  It is still hot enough that if one were able to travel to it, proximity would be fatal.

The wrap-around effect isn't really scientific, you might claim it as a curvature of space problem.  However, the plane really is flat.  When sailing, ships on the horizon are just really tiny, as opposed to only being able to see the crow's nest, as the rest of the ship is obscured.

The plane tilt will cause seasonal effect farther away from the equator, because as the plane tilt brings the northern half closer to the sun, getting it more heat.  Technically, there's a little problem with what happens to the southern half, since it is technically, just north of the northern half, if you get our meaning.  Somehow it all works out though.  Perhaps the wrap-around effect only works east-west, and not along the northern/southern borders.  it's too cold there to find out.

The last problem to solve is the whole distance of the sun to the plane, size of the world, and the appearance of night (aka lack of visible sunlight).  Since the world isn't round, the sun can't hide behind the other half.  If the world width is very wide, and the sun height is not very high, then as the sun recedes from your position, it will be mostly obscured from view due to the landscape.  At most, there will be a glow on the horizon all night.
