4.18 is way to old.  Either base your work on the 5.0 (which is 
already getting old) or use recent snapshots or even the 
anonymous CVS version.

For gdb yes.  It comes with the source (the GDB Internals manual) as
the User manual does.

Nothing for the GUI part (yet).

Use SOurce Navigator.  It can be downloaded from the net.
Look at sources.redhat.com

There are levels of verbosity.  Try "set remotedebug 2"
In newer releases it is "set debug remote 2".

And please, read the manuals and use the "help" command.

Use "grep" in your sources and you'll find them.
Your life will be considerably easier if you download and use
Source Navigator.

Good luck.
