I think what you are asking for is to make the background be plain
black (or plain white). For the image you have i'd select the red
regions with the Happy Stick / Fuzzzy Select Tool (use shift to keep
adding to a selection, clicking on different parts of the background).
When you've got most of it, you can use the freehand select tool (again
with shift), clicking on a point and then clicking again elsewhere to
make a straight line along the edge of th ebook.

When everything outside the book is selected, use select->grow
selection by 1 or 2 pixels, then feather the selection by 1.5 or maybe
even 2 or 3 pixels, to give a soft edge, and then use control-, or
control-. (control and comma at the same time) to fill the selection
with the foreground or background from the toolbox (or drag the colour
swatch onto the selection if you prefer).

You can use Undo if you make a mistake.

There are more complicated ways to do this with layers and layer masks,
but they are much harder when you're just starting out with gimp.  You
could also try and use the erasor, but i don't recommend that because f
you make a mistake early on and don't notice it, you're stuck.

Hope this helps.
