The HQ Catalogs only ask you to install the maps paths for the local workstation when you use the library interactively, for network rendering you can run one time the library on the node to setup the maps or copy all /maps to a shared map directory on your network.
For forest textures, it is a similar case, when you run forest will ask you to add maps maps to the map search list. This question it is asked only once time, so you can skip it and configure your shared maps by hand.
