This is if you need to get maps onto your GPS. If you just want to transpose coordinates onto your computer, Ingrid may have suggested the next logical step.
Birds eye view:
1) Get Data for your area (USGS, etcetera)
2) Process Data for your area (GPSMapEdit, Global Mapper, etcetera)
3) Compile Data for your area (cGPSMapper,)
4) Install Maps compiled from Data (MapSource, MapSetToolKit, etcetera)
OR
5) Find pre-compiled Open Street Maps (http://downloads.cloudmade.com/oceania/polynesia/american_samoa)
Steps 1-4 are covered in the 'Creating a Topo' tutorial (http://www.gpsfiledepot.com/tutorials/how-to-create-garmin-topo-maps/), although it's quite lengthy and takes a bit of time to get familiar with it all. It's the best 'long term' solution if you need something that isn't already available.
Step 5 is fairly simple, requiring only knowledge of how to get a compiled map on your Garmin device. (All you really need is american_samoa.img.zip)
This reply isn't real detailed. Once you decide which way to go, please post a followup question if need be.
Cheers!
