Let $G$ be a finitely generated Fuchsian group, and let $\mathcal{F}$ denote the Dirichlet Fundamental domain of $G$ with respect to $0$ in the Poincare disc model. 
Assume throughout that $\mathcal{F}$ is non-compact. 

I am interested in properties of $G$, and how these properties are connected with Poincare's Theorem. Here are my questions:

1) Is $G$ the free product of elementary hyperbolic, parabolic and elliptic subgroups? It is true for SL(2,Z). Moreover, it holds under the stronger assumptions in 2).

2) Assume that $G$ has no elliptic elements. Then $G$ is free (because $G$ is  fundamental group of a non-compact surface) and thus, $\mathcal{F}$ has vertices only at the boundary of hyperbolic space. Can we derive this property of the vertices from Poincare's Theorem?

3) Assume that $G$ is of the second kind (that is, the limit set of $G$ is not equal to the boundary of hyperbolic space). Then in particular $\mathcal{F}$ is non-compact. Is it true that the sides of $\mathcal{F}$ are pairwise disjoint, except (possibly) the sides paired by elliptic elements?
