Given an ellipse $(C)$: $\frac{x^{2}}{3m} + \frac{y^{2}}{m} = 1 (m > 0)$ with the length of its major axis being $2\sqrt{6}$, and $O$ is the coordinate origin.
(I) Find the equation and eccentricity of the ellipse $(C)$;
(II) Let moving line $(l)$ intersect with the $y$-axis at point $B$, and the symmetric point $P(3, 0)$ about line $(l)$ lies on the ellipse $(C)$. Find the minimum value of $|OB|$.
