Many good questions generate some degree of opinion based on expert experience, but answers to this question will tend to be almost entirely based on opinions, rather than facts, references, or specific expertise. If this question can be reworded to fit the rules in the help center, please edit the question.
Since it seems like you want to edit Shapefiles, I would recommend using a desktop GIS. Have a look at QGIS which provides the basemaps you are looking for through the OpenLayers plugin.
OpenLayers I think, but you will need to work with geoserver or mapserver, though. QGis would be a much more complete/easy application in any case.
Hope this helps,
