When to refresh/overwrite a map service

Hello, two rather simple questions:

1. After an .mxd file is published as a map service to ArcGIS Server, the map service and the .mxd file are completely independent of each other, correct?  In that the .mxd can be deleted/renamed and the map service is not affected.

2. When is it appropriate to republish/overwrite a dynamic map service published from an .mxd?  For example, if edits are made to the data, does the .mxd need to be republished for the edits to display or will the map service pick the edits up automatically?
And what are some examples where a dynamic map service would have to be republished to reflect changes?  Change in symbology...?
Thank you
