In the rectangular coordinate system xOy, the parametric equation of line l is $$\begin{cases} x=3+ \sqrt {2}t \\ y=4+ \sqrt {2}t\end{cases}$$ (t is the parameter). Establish a polar coordinate system with the coordinate origin as the pole, the positive semi-axis of the x-axis as the polar axis, and having the same length unit as the rectangular coordinate system xOy. The polar coordinate equation of curve C is ρ=4sinθ.

1. Find the ordinary equation of line l and the rectangular coordinate equation of curve C.
2. Suppose curve C intersects line l at points A and B, and point M has coordinates (3, 4). Find the value of |MA|•|MB|.
