In the Cartesian coordinate system xOy, the equation of line l is $x-y+4=0$. The parametric equation for curve C is $\begin{cases} x= \sqrt {3}\cos\alpha \\ y=\sin\alpha \end{cases}$ (where $\alpha$ is the parameter).
(I) Given that in the polar coordinate system (using the same unit length as in the Cartesian coordinate system xOy, with the origin O as the pole and the positive x-axis as the polar axis), point P has polar coordinates (4, $\frac{\pi}{2}$). Determine the positional relationship between point P and line l.
(II) Suppose point Q is a moving point on curve C. Find the minimum distance from Q to line l.
