(I) Simplify and evaluate: $\log \_{ \frac {1}{3}} \sqrt {27}+\lg 25+\lg 4+7^{-\log \_{7}2}+(-0.98)^{0}$
(II) Given a point $P( \sqrt {2},- \sqrt {6})$ on the terminal side of angle $α$, evaluate: $\frac{\cos ( \frac {π}{2}+α)\cos (2π-α)+\sin (-α- \frac {π}{2})\cos (π-α)}{\sin (π+α)\cos ( \frac {π}{2}-α)}$.
