Can you tap and hold on the application (from the app list) and select uninstall?
MS does prohibit the the installation of crapware from their phones.
We want you to be able to enjoy your phone and all the features and applications it offers, Virtuous. What is it that you don't like about VZ Navigator and Verizon? VZ Navigator can't be removed from the phone, but you can currently try it free for 30 days http://vz.to/1af2lur. I'd be happy to help you enjoy it.
