I don't know of any configurator, but it's not really necessary. You just buy as many block/modules as you have cables. The product catalog pages will show you the various module options. You probably just need a telco module and 1-2 network (RJ45) blocks. Leave the coax connections for whichever provider you have to deal with - don't buy splitters/amps for them - let the installer do it.
Stick with the major brands (Leviton, Legrand/OnQ). You want compatible modules to be available for years to come. I've been unimpressed with some of the "cheap" brands in terms of build quality.
