There is setting for the names (but I think there have been people on the OSMand mailing list having issues with it). The English names would also have to be present in the OSM data (not for any particular technical reason, just as far as I'm aware that is the only source of names the devs use for the maps).

Also, the free version allows for 10 downloads, where updating a previously downloaded map (which might only be a region of a country) counts as one of them. But the paid version is only $8.
