Hi,

To answer your first question, if you click on "More", it should take 
you to the relevant entry in the Help Browser. If it doesn't, there is 
something wrong with your installation.

In your example, the reason that the Show[] command didn't work is that 
your previous commands didn't evaluate properly (you can tell this 
because the output of the Show[] command contains the unevaluated 
earlier commands, rather than the Graphics objects you would get if 
they had evaluated correctly.

I can't test your example because it doesn't include the definition of f.
