You can add a file to an email as an attachment: Trying to attach a file from SD Card to email
AFAIK Facebook does not allow you to share files. You can post text and images, but not files in general.
Twitter same as 2. above. You can post tweets - text up to 140 chars long. You can also post pictures via TwitPic. But you cant share files in general.
You could upload a file to some file sharing site (you'd need account for that) and then share url via Facebook or Twitter.
