There has been indeed much development in the dynamics of several complex variables in the last 20 years or so.  The directions which the subject took focus on different aspects. E.g., is one interested in maps in the affine space, projective space  or more general complex manifolds?  Are the maps holomorphic diffeomorphisms, just holomorphic endomorphisms or birational maps?  Polynomial, rational or transcendental (where this distinction makes sense)? What are invariant objects associated with the maps of interest: attracting/repelling sets, measures, currents etc.? The papers studying such problems  are numerous (and many of them carry 32H50 as their primary MSC classification). In addition to sources already mentioned, let me recommend somewhat more up-to-date accounts of these subjects: 

MR2572393 Holomorphic dynamical systems.
Lectures given at the C.I.M.E. Summer School held in Cetraro, July 7–12, 2008. Edited by Graziano Gentili, Jacques Guenot and Giorgio Patrizio. Lecture Notes in Mathematics, 1998. Springer-Verlag, Berlin; Fondazione C.I.M.E., Florence, 2010. xiv+342 pp. ISBN: 978-3-642-13170-7 

This book contains several tutorials by people involved in the development of the subject:
Marco Abate, Discrete holomorphic local dynamical systems (1–55) MR2648687; 
Eric Bedford, Dynamics of rational surface automorphisms (57–104) MR2648688; 
Marco Brunella, Uniformisation of foliations by curves (105–163) MR2648689; 
Tien-Cuong Dinh and Nessim Sibony, Dynamics in several complex variables: endomorphisms of projective spaces and polynomial-like mappings (165–294) MR2648690; 
Dierk Schleicher, Dynamics of entire functions (295–339) MR2648691

If some particular subject catches your attention, look up the bibliography on it given in these tutorials. It is a matter of taste to decide which papers are "the best", although those mentioned above (in Alex Eremenko's and in my answer) are very well written. It helps to read French, as many papers in dynamics of several complex variables are written in this language.
