Thanks again, eschwartz.

So, for instance, if you change the metadata with an epub, then convert to mobi, the mobi will contain the metadata you changed but the epub won't?

If one book has different formats with different metadata, how can you look at the embedded metadata in the different formats?

Embed Metadata and Polish book. All metadata that can be updated will be embedded into the library copies. (You can choose to restrict this to specific formats.) Certain types of metadata are not supported by certain formats -- notably, only EPUB and AZW3 support updating covers.
This sounds like what I need, and I've found and added them to the toolbar now. It seems like I can use this so I won't have to convert to embed changed metadata.

If I use say send to device will it only embed on the copy being sent or will it also embed on the calibre file?

Identifiers, like any other metadata, are derived from the library metadata. The only exception I can think of is mobi-asin, which is derived from a mobi header. That header can be set from the amazon|asin|mobi-asin identifier using the Quality Check plugin, which can be useful for things like goodreads/store linking on-device.
Here's what's happening with the identifiers- When I download metadata it often provides various identifiers like amazon, etc. However, when I convert, even though the other metadata I'd changed embeds, the identifiers don't and change back to what they were before I'd downloaded metadata (in other words, it erases the ones that had been added).

At least, this seems to be the case. I tested it all by converting, manually moving the new file to a non-calibre location, deleting the book from calibre and adding the new file to calibre as a new book then checking the metadata.
