Ok I'll try to answer all the questions I can in the short amount
of time I have...

Glade 3 docs here are helpful but out of date:
   http://glade.gnome.org/docs/index.html

Come to #glade3 irc.gnome.org in the week and I'll be around
(and Juan and Vincent too...)... we can easily help you through the
steps of setting up an xml file to have your widget(s) recognized
by glade (also look at plugins/gtk+/ directory of the glade tarball
to see the gtk+ plugin for an example, it huge because it includes
all gtk+ widgets & support code but at least you can get references).

The directory is exported by a .pc file, it could depend on where
the vendor decided to install glade, probably /usr/share/glade3/...

User defined catalogs in home dirs could be easily doable, maybe
by adding a simple env var "GLADE_CATALOG_DIRS" or such, you're
welcome to send us a patch ofcourse or at least a bugzilla entry :)

These are 2 different programs, I dont see why they would try to
install files in the same place.
