Given the function $f(x)= \frac {m}{x+1}+n\ln x(m,n$ are constants$)$, its graph has a tangent line equation at $x=1$ of $x+y-2=0$.
(1) Determine the monotonicity of the function $f(x)$;
(2) Given $p∈(0,1)$, and $f(p)=2$, if for any $x∈(p,1)$, any $t∈[ \frac {1}{2},2]$, either $f(x)≥slant t^{3}-t^{2}-2at+2$ or $f(x)≤slant t^{3}-t^{2}-2at+2$ holds true, find the range of values for the real number $a$.
