I am by no means a GTK expert, but, I think that you might like the
gtk_tree_model_foreach() function, which lets you give it a function to
run with each item in the model (look in
plugins/mtpdevice/rb-mtp-source.c).  Also, since the RhythmDBQueryModel
isn't quite a real tree model, you probably need to pass it as
GTK_TREE_MODEL(model) to whatever function you decide to use, since that
function is expecting a GTKTreeModel, and is getting a
RhythmDBQueryModel.

As far as keeping track of changes in RB source, SVN is probably the
best way.  Take a look at http://live.gnome.org/Rhythmbox/FAQ for info
about checking out HEAD.
