- What is the best way to: load/download it into Android, and
- what is the best way to show them on a Google Maps?

For such a big amount of Markers I suggest you give KML Layers a shot.
With Google Maps you can either have google render all markers for you, (default: KMLLayers) or you can rely on GeoXML3 for client side parsing.
The same applies to Android Google Maps. Layers can easily be added using this: How to draw a path on a map using kml file?
