I'll throw in some keywords which might help you get started.

Google up devhelp. More gnome (and therefore C in a lot of cases).  You
can also bind a key to "manual-entry" for word at point assuming you
have the required manual pages. Also consider eldoc for context
sensitive help if the required functions can be written for the language
you are interested in.

Use cscope and also consider etags. I then have:
,----
| (require 'etags-select)
| (global-set-key "\M-." 'etags-select-find-tag-at-point)
| (global-set-key "\M-#" 'pop-tag-mark)
`----

Good for C/C++ and elisp and php and ... I think.

Also there is a commercial offering :

The standard c++browser for emacs is, I believe, ebrowse but I have no
idea as to its status or abilities.

http://www.gnu.org/software/emacs/manual/ebrowse.html

Lastly look at Cedet. I never really got autocompletion working properly
before I changed to another project but it looks promising.

I'm not sure, personally, about ecb. It is configurable but the default
layout takes a lot of real estate for little practical gain in my
opinion. 

I would love to see a collection of what others have achieved with emacs
as a C/C++ IDE.

Lastly, if you dont get what you want look up using eclipse - it's IDE
features for things like refactoring, context help are much superior to
Emacs at this stage IMO. The disadvantages are ... its not emacs.
