Yes, you must convert your existing RC files to CSS files.

There is much information about this on the gtk+3 site,
http://developer.gnome.org/gtk3/stable/gtk-migrating-GtkStyleContext.html
and its subsections.

If you have specific questions about CSS files, don't expect a reply 
from me. I don't know very much about them. Of course you're welcome to 
ask on gtkmm-list, and hope someone else will reply, but I suspect most 
of the expertise in this area is among the gtk+ developers. 
gtk-app-devel-list is probably better for such questions.
