No, you don't need to var scope your arguments. Unless you have some reason for wanting to have a copy of the arguments you don't need to worry about duplicating or var-scoping them.
As far as how CFC's behave for each user, as long as you are var-scoping your local variables you will be fine. And yes you're right, if you instantiate a CFC into the application scope, there is only one instance of the CFC and all users of the application are using that single instance. This is an implementation of the Singleton design pattern (if you have any interest in patterns). I wrote an article for Techrepublic a while back that talks about CFCs, locking, and persistent scopes. It might help make some of this gel further.
