I know that the metadata is supposed to be in the .epub file as well, but maybe calibre isn't putting it in the .epub -- maybe it is just stashing it in the .opf? I'm not sure. I'll try loading up some of my .epubs in a Sigil and see what metadata is there.

Perhaps I didn't explain well enough. When you add Series info to a book in calibre it is stored in the .opf file, but the epub itself is not updated.
When using calibre's Save-to-disk or Send-to-device the metadata contained in the calibre .opf file is used to update the metadata contained inside the epub's internal opf file - where your reading device should be able to find it.
However, using your PC's operating system copy and/or drag-drop will not do this metadata updating, consequently your epub may not contain all the calibre metadata (e.g. Series), therefore your reading device will not see it. No reading device is capable of directly reading the individual
BookName.opf files contained in the calibre book directories, so there is no point copying them.
