Given the equation of ellipse C is $$\frac {x^{2}}{a^{2}}+ \frac {y^{2}}{b^{2}}=1$$ (where $a>b>0$), and its left and right foci are $F_{1}$ and $F_{2}$ respectively. If the sum of distances from a point $P(1, \frac { \sqrt {3}}{2})$ on ellipse C to $F_{1}$ and $F_{2}$ equals 4.  
(Ⅰ) Write down the equation of ellipse C and the coordinates of the foci;  
(Ⅱ) Let point Q be a moving point on ellipse C, find the equation of the trajectory of the midpoint T of segment $F_{1}Q$;  
(Ⅲ) Line l passes through the fixed point M(0, 2), and intersects ellipse C at two distinct points A and B. If $\angle AOB$ is acute (where O is the origin), find the range of values for the slope $k_{0}$ of line l.
