ASP.NET MVC 5 Layering?

I'm developing an Application with ASP.NET MVC 5, EF (5 or 6), Oracle 11g and Kendo UI.

Now, I want to layer (architecture) the application. So, Please give me guidance on how to layer the project and different ways of layering the projects.

I've read about Generic Repository Pattern and I have following questions,

1. Is it good to use in my situation?
2. Is it good to use EF Class in the View ? or Is it good to use Model class (Not the EF Class) and Automapper which converts EF Class to Model Class?
3. Is it good to use Log4Net for Logging ?

Or Is there any other Pattern we can use it ?

I'm sorry, this might be simple question but I'm new to Layering (Architect) the Project. So, Please guide me how to layer the project ?

Thanks,

Prakash.
