The not fixing of ISBNs is a bug, which will be fixed in the next release.
isbn:ss0743471563 is valid because calibre will automatically strip the invalid charaacters (or at least, it will once the above bug is fixed).
You can put any ids you like into that field, but only one id of each type. If you want to refer to an amazon page, use amazon:1234567890. You will see in the next release that amazon ids are automatically converted into links to the amazon page in the book details panel.
