Given the circle C: $(x-3)^2+(y-4)^2=4$, and a line $l_{1}$ passing through the fixed point A (1, 0).

(I) If $l_{1}$ is tangent to circle C, find the equation of $l_{1}$.

(II) If $l_{1}$ intersects with circle C at points P and Q, find the maximum value of the area of triangle CPQ and the equation of $l_{1}$ at that time.
