Your assumptions are right.
You could try downloading the free chart software from Maptech
After you have installed the maptech software, then download the free charts you want from the NOAA site and unpack them to the Chart directory that Maptech creates when it is installed.
You can then plan and plot out routes and download them to your GPS.
