I think you've set the "Has default" property to Yes on some
widget, but you forgot to set the "Can default" property
to Yes on that same widget.
In short, you created a default widget that can't be the default and
gtk happily complains about that. Check your glade file to fix it.

See the answer to your third "problem" :)

Use a CellRendererToggle. There's a tutorial on the pygtk website:
http://pygtk.org/pygtk2tutorial/sec-CellRenderers.html (scroll all the
way down that page to "Figure 14.6. Editable and Activatable Cells")

You'll probably get faster/better answers to you pygtk questions on the
pygtk mailing list: http://www.daa.com.au/mailman/listinfo/pygtk

Have fun,
