In the second part, I generalize the above structures to the case of Riemann surfaces \Sigma_{g,s,n} -- R.s. with holes and decorated boundary cusps on hole boundaries. There, an interesting phenomenon occurs: (i) we have to consider generalized cluster transformations; (ii) we can establish 1-1 correspondence between (extended) shear coordinates and lambda-lengths, so we can investigate both Poisson and symplectic structures on the both sets of variables.
