Do you mean the full potential list of values that can be chosen for each field (irrespective of user) or are you referring to the full list of profile settings against a particular user?
If you are talking about settings for a user, you can try the following calls:
http://community.lithium.com/community-name/restapi/vc/users/id/43/profiles
http://community.lithium.com/community-name/restapi/vc/users/login/john_doe/profiles
I don't know if the other option is possible but if that is what you were after please reply back and we can investigate further or one of my other colleagues can post an answer.
