In my MVC 3.0 application, I use the database first schema of entity framework.
In the views, I want to add validation for input. Should I create a new model type for the entity that I need to validate, so that I can add validation attributes on it? Those entity types are generated by entity framework.
No, you should create a buddy class with the MetadataType attribute that refers to a class with your validation. Check out this example:

Specifically the section labeled Using Data Annotation Validators with the Entity Framework.
