Configuring Gnome apps without Gnome

I hope that this is the right list. There is no gnome-users list on
mail.gnome.org.

I need to configure some global Gnome settings for use in F-Spot, Zim,
and other GTK/Gnome applications, however as a KDE user I do not have
the full Gnome desktop installed and therefore I do not have the
configuration dialogs. Googling for Gnome configuration setting yields
little results, presumably, Gnome users don't do that! Please assist
me in locating the proper files and syntax for configuring:
1) Single click as opposed to double click to activate items.
2) Large icons with no text.
3) More will come as we begin to use the applications in production.

Thanks!
