1) Yes, we still use Google Maps, but try to use it less (remove Google Maps functionality from some places and do not add any new features that uses Google Maps).
If Google Maps sales team would insist - we would remove it even faster and replace with OpenCageData. But so far Google Maps works and does not require new code.
3) Does "OSM" mean OpenStreetMaps? I did not try it. Does OpenStreetMaps API have geocoding? http://wiki.openstreetmap.org/wiki/API_v0.6 does not contain words "geocoding" or "geocode"
