The warning on edit-content-form.php has been patched and will be fixed in the next release. http://github.com/voceconnect/cms-press/commit/6c48de8071dfdd662c29a0affda64e94841d6db3
I’ve also created a ticket for the problem with the taxonomy not showing for the page in WP 2.9. It should also be fixed in the next release, hopefully sometime this week. http://github.com/voceconnect/cms-press/issues/issue/25
Can you provide a list of plugins your running and who your hosting provider is?
