In the Cartesian coordinate system $xOy$, it is known that Circle $M$ is defined by the equation $x^2 + y^2 - 8x + 6 = 0$. A line passing through point $P(0, 2)$ with a slope of $k$ intersects Circle $M$ at two different points $A$ and $B$, with the midpoint of line segment $AB$ being $N$.
(1) Determine the range of values for $k$;
(2) If $ON \parallel MP$, calculate the value of $k$.
