If it were me and I had LOTS of names etc, I'd export them as a CSV (something that can be imported into Excel/OO maybe? Google?) and then import the CSV into a spreadsheet.

Once in the spreadsheet you could mail merge into a Word/OO document. You can either order them in the spreadsheet (for indexing) or Word. Spreadsheet would be easier. You can add Indexes/TOC in Word if required.

Import the Word/OO document into Calibre.

OR

If you want to bypass the mail merge, you could export the spreadsheet as an RTF and import that into Calibre.

Edited: OH...wait. You probably can't save a spreadsheet as an RTF. But you could do a HTML file. That may be it. Do the spreadsheet, format, remove superfluous fields and save as HTML.
