Web Settings and different models

I am working on a web app that will have administrator options which in turn will populate a select list on the client
side of the application.

Being new to Rails I have two questions...

I have a table of states and a table of countries. If I understand things correctly if I want to a list like states and make
it sticky I will need to create a model for each?

The application has multiple options that can be set such as Private or Public, City or Country, etc. Do I need to make
a table for each option and then have a model for each to make that list sticky when the form is called up?

Thank you in advance for your help.
