Given that the pole of the polar coordinate system is at the origin O of the rectangular coordinate system, the polar axis coincides with the positive semi-axis of the x-axis, and the units of length are the same. The parametric equation of circle C is $$\begin{cases} x=1+2cos\alpha \\ y=-1+2sin\alpha \end{cases}$$ (α is the parameter), and the polar coordinates of point Q are $$(2， \frac {7π}{4})$$.
(1) Convert the parametric equation of circle C into a polar coordinate equation;
(2) If point P is any point on circle C, find the minimum value of the distance between points P and Q.
