Given that the sum of the first $n$ terms of a sequence ${a_{n}}$ is $S_{n}$, and $S_{n}+ \frac {1}{2}a_{n}=1(n∈N^{*). The sequence ${a_{n}}$ is:
1. Find the general term formula of the sequence ${a_{n}}$.
2. Let $b_{n}=\log_{ \frac {1}{3}} \frac {a_{n+1}}{2}(n∈N^{*})$, and $T_{n}= \frac {1}{b_{1}b_{2}}+ \frac {1}{b_{2}b_{3}}+…+ \frac {1}{b_{n}b_{n+1}}$, find $T_{n}$.
