True. Some hints:
Use apropos (C-h a) and grep to find what's in the lisp
subdirectory.
Get the Lisp Directory and the associated commands to search it
(the URL should be in the Emacs FAQ). This is a data-base of
user-written extensions to Emacs.
Post a question to gnu.emacs.help (or write to
help-gnu-emacs AT prep DOT ai DOT mit DOT edu, if you cannot access that group). There
are a few people there (not me, of course) who will give you very good
advice.

You are doing just fine, congratulations.

Either .el or .elc (the latter is byte-compiled and runs faster).

You need to write something similar for C++-mode that looks into the
appropriate C++ info files (iostream, libgpp etc.).

Not that I know of.

I have never seen an Info file about C or C++ as a *language*. Until
such a thing gets written, you cannot look it up.

Yes, you can, by changing the code a bit. But do you really need that?
I find it very useful to get a chance at what my Golem thinks I need to
know before it jumps into the blue. A single RET is not too much, after
all.

Well, why won't you try writing this?

I've added this to my _emacs when John posted it, so the next DJGPP
distribution will have it in the _emacs.xmpl file.

Use DJTAR. It is excellent for these tasks. You should have no problems
installing ELisp manual with DJTAR. There might be some .texi files that
will make trouble, but you can just skip them (press RET when DJTAR
prompts for an alternative filename), because all you need is the .info-*
files.
(Btw, for the record: I don't have Linux on my machines. I do everything
either in DOS or Windows 3.X/9X.)
