Not entirely.

Don't add edonkey to inetd, that's just asking for trouble.

Just reload the daemon you're reconfiguring instead. In this case,
as root (using su[1]), do /etc/init.d/inetd reload. If a particular
daemon doesn't have a reload, restart works just as well (though can
potentially take longer).

Right.

Personal firewalls aren't. http://www.samspade.org/d/firewalls.html
Using a reasonably secure OS is more effective than a Windows box
running a personal firewall. Don't run any network services that you
don't use and you should be OK in Linux.

edonkey has no options to run as a daemon, this won't help. Programs
will open their own ports as needed.
Try to undo what you've done, and go look through the edonkey faq to
see why you're getting a low-id. If you're not getting a low-id,
forget about it, nothing's wrong.
Don't feel bad, many people have a rough start. ESR wrote an essay
entitled "How to ask questions the smart way," which I think is
misnamed. It really should be, "How to troubleshoot effectively."
Either way, it's on the web here:
http://www.catb.org/~esr/faqs/smart-questions.html
Hope this helps!
[1] If you log in as root, break that habit immediately. Seriously.
Just use su instead, or if you need an X program as root, use su -m
