In the arithmetic sequence $\{a\_n\}$, the common difference $d \neq 0$, $a\_1=7$, and $a\_2$, $a\_5$, $a\_{10}$ form a geometric sequence.
(1) Find the general term formula of the sequence $\{a\_n\}$ and its sum of the first $n$ terms $S\_n$;
(2) If $b\_n= \frac {5}{a\_n \cdot a\_{n+1}}$, find the sum of the first $n$ terms of the sequence $\{b\_n\}$, denoted as $T\_n$.
