Is there a good wireframe tool to use with Kendo UI?

[Dave]

I plan to create an ASP.NET MVC3 based website, that uses EF 5.0 for database access, built using VS2012 and .NET 4.5.

A couple questions please-

1. Is Kendo UI the best choice for an ASP.NET MVC3 website that must run on IE7 and works with .NET 4.5?
2. Is there a decent wireframe or website mocking tool that I can from within VS2012 that will later work with Kendo UI?

Thanks, Dave
