Thank you for contacting us!
I will straight answer your questions.
We have delayed the release of VS extensions for Visual Studio 2013 due to a extra work load on our side. We are currently working on the task and we are expecting to publish the new version of the VS extensions till the end of the year through the Visual Studio Gallery. If you have the VS extensions installed you will receive a notification through Visual Studio and then you can install them in Visual Studio 2013 using the Extensions and Updates utility in Visual Studio.
We have removed the ASP.NET identity related code on a purpose so that you don't get redundant code. We plan to follow the same approach with the VS extensions for Visual Studio 2013. If you want to make use of the default MVC functionality available in the default MVC templates you can create a default project and then convert it to Kendo using the conversion wizard available in the Telerik menu,
We will consider you feedback in regard to the jQuery css files.
I hope the information provided helps. Should you have any further inquires don't hesitate to contact us again.
