Which Microsoft Azure version?

Question

I want to use remote notifications for my Android app using Xamarin. Now I found a way implementing this through Microsoft Azure. So I am a student and have a Microsoft DreamSpark account. Now i thought, I could download Azure via DreamSpark, but which of these packages I need?

• Microsoft Azure Authoring Tools
• Microsoft Azure Client Libraries for .NET
• Microsoft Azure Emulator
• Microsoft Azure LightSwitch Tools for Visual Studio 2013
• Microsoft Azure Mobile SDK
• Microsoft Azure SDK for .NET 2.5
• Microsoft Azure Storage Emulator
• Microsoft Azure Storage Tools
• Microsoft Azure Tools for Visual Studio

I don't think I need a Mobile SDK, do I?
