Given the line $l: y = x + m$ ($m \in \mathbb{R}$), and the hyperbola $E: \frac{x^2}{2} - \frac{y^2}{b^2} = 1$ ($b > 0$).

(1) If the line $l$ is parallel to one of the asymptotes of the hyperbola $E$, find the eccentricity of the hyperbola $E$.

(2) If the line $l$ passes through the right focus $F_2$ of the hyperbola and intersects the hyperbola at points $P$ and $Q$, and $\overrightarrow{FP} = \frac{1}{5} \overrightarrow{FQ}$, find the equation of the hyperbola.
