You need a server that supports transactions :

  - GeoServer
  - TinyOWS
  see the example : 
http://openlayers.org/dev/examples/wfs-protocol-transactions.html

  - FeatureServer (uses MapFish protocol)
  see a demo : http://dev4.mapgears.com/bdga-fs/

  The FS demo also shows a way to edit feature's attributes.

Yes.  Look at the following example and search the source for the 
externalGraphic property.
