Not necessarily. You can go with standard Open Source things like Node and run on Linux. Another option is ASP.NET 5 that can run on Linux/Mac and use the free Visual Studio Code editor on Linux or Mac. No Windows needed. Angular, JQuery, and Bootstrap are not needed, but make some things easier. If sticking with your list, I'd use Entity Framework over NHibernate.
