Given the function $f(x)=\frac{1-a}{2}x^{2}+ax-\ln x (a\in R)$.
(1) Discuss the monotonicity of the function $f(x)$ when $a > 1$.
(2) If for any $a\in(3,4)$ and any $x_{1}$, $x_{2}\in[1,2]$, the inequality $\frac{(a^{2}-1)m}{2}+\ln 2 > |f(x_{1})-f(x_{2})|$ always holds, find the range of values for the real number $m$.
