I really like this book by Frank Luna. It's got a pretty solid progression from basics to more advanced topics in the first two-thirds, and the final third of the book focuses on some cool applied techniques.

When I made the move to D3D11 I picked up Practical Rendering and Computation with Direct3D11. I enjoyed it and would recommend it, as the first half of the book has a pretty good overview of the API (especially organization of resources, which can get confusing). The authors are active on these forums too (MJP, Jason Z).

There are some excellent resources online too; rastertek provides lots of information on commonly used DirectX techniques http://www.rastertek.com/tutindex.html

If you are already familiar with OpenGL you shouldn't need a book that much because you should already know most of the rendering stuff all it is is an API switch. Generally the MSDN documentation on DX is decent just don't forget to read all of the remarks section on it's pages.

The only real thing to learn is which parts of the API correspond to what parts in the GL API that you already should know.

Also seeing you are using windows 8 SDK you can skip all the sections on PIX unless you have a full version of Visual Studio 2012 or higher as PIX doesn't understand the DX11.1 or higher runtime that is included with that SDK.

+1 vote for Frank Luna "Introduction to 3D Game Programming with Direct3D 11" for introduction and turorials

AND

+1 vote for "Practical Rendering and Computation with Direct3D 11" as API reference book (MSDN library imo is not enough, it's too much cryptic )

of course don't forget the tons of online free materials, like:

- D3D book http://content.gpwiki.org/index.php/D3DBook:Table_of_Contents

- rastertek and braynzarsoft tutorials

- the "legacy" microsoft DirectX SDK

- AMD & NVIDIA SDKs
