Answer 1

There appears to be a corrupted portlet manager in your site; it is missing the "group" category. This doesn't normally happen, though.
You could open the plone.app.portlets.browser.manage module, and insert a PDB debug prompt, to see what manager this is. Look for the plone.app.portlets egg in your bin/instance script to find its path, then open the plone/app/portlets/browser/manage.py that in your favourite text editor. Insert your import pdb; pdb.set_trace() line before line 213, run your plone site in foreground mode (bin/instance fg) and start poking around. manager.__name__ should be interesting, for example, to figure out what manager this is.
You could then try to repair this by inserting an empty category mapper:
from plone.portlets.storage import PortletCategoryMapping
from plone.portlets.constants import GROUP_CATEGORY
column[GROUP_CATEGORY] = PortletCategoryMapping()
You may want to be careful with that, though; there may be other things broken here.
