Given an arithmetic sequence $\{a_n\}$, the sum of the first $n$ terms is $S_n$, and it is known that $S_4=16$, $S_6=36$.  
(1) Find $a_n$;  
(2) Let the sequence $\{b_n\}$ satisfy $b_n=q^{a_n}$ ($q\in \mathbb{R}, q>0$), and $T_n= \frac {1}{b_{1}b_{2}}+ \frac {1}{b_{2}b_{3}}+\ldots+ \frac {1}{b_{n}b_{n+1}}$, find $T_n$.
