Answer 1

You can use binwalk --dd=".*" file_name. Above command instructs Binwalk to extract any file type.

It seems Binwalk with -e just extract files with known or complete header.

Answer 2

The firmware you have is from Amazon Dash. I know this from the MD5 hash. Many people have done a great done reversing it. Google around and also check this out: https://hackaday.io/project/5832-exploring-amazon-dash-button.
