WPF MVVM entity framework (model)

Hello Everyone

I trying to redo my project to follow the MVVM pattern. For that reason i have started a new project.

So far i have added ADO.Net entity data model, meaning the entity framework has been added to my reference. 

My question is:

Since i am working with Mysql, is it still required to add the MySql.Data.dll to the project in references? if yes why?

Secondly, now that the entity framework and if needed the MySql.Data.dll are done would that mean that the "Model" part of the MVVM pattern is done? or do i need to do more like my declare my connection string? would my SELECT, UPDATE, INSERT and DELETE statements be in the Model or the ViewModel?

Lastly, Since i want a clear definition on the Model, ModelView and View part in my project, if I created a folder called Model what should be added to it?
