In X its usually enough to select text and press the middle mouse botton
on a different window (vim insert mode, shell whatsoever). This will
copy paste the selected text.

Write a script such as

#!/bin/sh
{ echo ; date ;  xclip -o } >> ~/useful-text.db

If you copy past from FireFox very much - it has plugins which copy the
selected text and add the url for reference. You may want to digg for
those.

Then bind it to a key using your window manager.

If you want to automate it - no clue how to select line 10-15
automatically - sorry.
