Guide for creating EPiServer module in MVC

For a client I really would like to add some new module at the top of the CMS navigation bar (after user groups). With some tutorials and trail and error I managed to get the module in the navigation and also it loads a page. Still this is a view without any style or layout. 

I've read some articles and tried to add shell sources. This works as expected. Still when I try and add

 @Html.Raw(Html.ShellInitializationScript())
 @Html.CreatePlatformNavigationMenu()

I get problems in different versions with System.Web.MVC. I found an article to ignore those warnings but then at runtime I get errors like;

'HtmlHelper' does not contain a definition for 'ShellInitializationScript' 

So my questions to you;

Is it possible to develop modules in MVC? I also noticed geta had a plugin but that is gone now?

1. Is there a up to date guide/tutorial you suggest?
2. Is there a layout from EPiServer I can use instead of reinventing the wheel?
   1. Anyone stumble upon this mismatch in System.Web.MVC and knows how to solve it?
