Let the function $f(x) = \frac{bx}{\ln x} - ax$, where $e$ is the base of the natural logarithm.

(I) If the tangent line to the graph of the function $f(x)$ at the point $(e^2, f(e^2))$ is $3x + 4y - e^2 = 0$, find the values of the real numbers $a$ and $b$.

(II) When $b = 1$, if there exist $x_1, x_2 \in [e, e^2]$ such that $f(x_1) \leq f'(x_2) + a$ holds, find the minimum value of the real number $a$.
