Ok, that is getting better.

That is all?  Gnome is known to have issues running more than one session
as a user (see below).  After trying what I suggest below, try making your
xstartup:

unset SESSION_MANAGER
exec /etc/X11/xinit/xinitrc

Ok, try this.  Close your VNC servers, log out of your local X (going back
to the login screen), then go to another console (ctrl-alt-F1), log in,
then try to start the vncserver.  This will make sure there are no
multi-session GNOME issues.
