Given that the sum of the first $n$ terms of the sequence $\{a\_n\}$ is $S\_n$, and for any positive integer $n$, $a\_n= \frac {3}{4}S\_n+2$ holds.
1. Let $b\_n=\log _{2}a\_n$, find the general term formula of the sequence $\{b\_n\}$.
2. Let $c\_n= \frac {1}{b\_n b_{n+1}}$, find the sum of the first $n$ terms of the sequence $\{c\_n\}$, denoted as $T\_n$.
