A:
Garmin maps are copyrighted binary files. Extracting this data without a license to do so is illegal. Don't do it.
The information you seek may be available from the USGS site for free in an easy-to-use text format: http://geonames.usgs.gov/domestic/
Alternatively, consider using one of google or yahoo's excellent geolocation APIs.
