How to edit GNOME menus ?
GNOME presents you with its own menu by the package gnome-menus.
Standard Debian menu provided by menu is hidden by default.
You can edit Gnome menu by: "System" -> "Preferences" -> "Main menu". This will launch GUI menu edit program provided by alacarte.
An seemingly old tool named gmenu-simple-editor in gnome-menus is normally not used. (As of 2005-10; Daniel Cardenas said : The debian menu system may wipe out Gnome specific menu settings when a new application (aka package) is installed.)
The following two links will probably be helpful:

How to change start-here.png icon files for lenny ?
You can not change main menu icon from Gnome foot to Debian easily using Configuration Editor under lenny. (For squeeze, you can use update-alternatives(8).)
Simplest method is to create a new theme by copying gnome and replacing Gnome foot by Debian swirl (created from /usr/share/pixmaps/debian-swirl-logo.svg with Gimp).
But I now use a hack by replacing gnome theme files in /usr/share/icons/gnome/*/places/start-here.png using dpkg-divert command. Something like:
$ dpkg-divert --divert /usr/share/icons/gnome/??x??/places/start-here.old.png --rename /usr/share/icons/gnome/??x??/places/start-here.png
To remove that diversion later, I need to do something like:
$ dpkg-divert --rename --remove /usr/share/icons/gnome/??x??/places/start-here.png
Although I wrote "??x??" in above script, actual command should have actual size like "22x22" in there.
To update menu:
$ ps aux|grep gnome-pane[l] osamu 26772 1.4 0.7 374728 22764 ? S 23:38 0:00 gnome-panel --sm-client-id ... $ kill -TERM 26772
Since this could get complicated, I made small package just to do this: http://people.debian.org/~osamu/debian/pool/main/debian-icon-theme_0.1_all.deb . Fetch it and do "dpkg -i debian-icon-theme_0.1_all.deb".
