How to Uninstall from Pages?

I’ve been trying the trial of Endnote with Pages '09. Lots of promise, I really wanted it to work, but there are still some serious game-stopping issues for me (many of them already mentioned in this forum). Until these are fixed, I’m afraid I have to not buy in to Endnote.

How do I uninstall the menu add-ins that are now in Pages '09? Will running the Endnote uninstaller (customizer, I believe it’s called) do this?
