I think that many people leave the books title in calibre alone, and ensure that the series info is correctly filled in.
However, they then use a feature of calibre called "plugboards" to ensure that when the book(s) are sent to their eReader, that the titles as displayed on the eReader are modified to include the series info.
This allows for both the easy management (including the retrieval of metadata) in calibre, and the simplicity of sorting by title on the eReader to see the series info.
See
