Given that the sum of the coefficients in the expansion of $(3x^{2}+ \sqrt {x})^{n}$ is $M$, the sum of the coefficients in the expansion of $(3x^{2}- \sqrt {x})^{n+5}$ is $N$, and the sum of the coefficients in the expansion of $(x+1)^{n}$ is $P$, with $M+N-P=2016$, find in the expansion of $(2x^{2}- \frac {1}{x^{2}})^{2n}$:  
(1) The term with the largest binomial coefficient;  
(2) The term with the largest absolute value of the coefficient.
