Answer 1

1. If you are targetting .NET 4 then you can get rid of a lot of this stuff. It would probably be easiest to create a brand new MVC project targetting 4.0 and look at the default web.config there.

2. If you are targetting .NET 3.5 everything in here looks pretty standard. I'm assuming you are using membership, roles, profiles, the various namespaces etc. in your application.

   You might be able to get rid of some of the reference assemblies (System.Data.Linq, System.Xml.Linq, etc) if you are not using their features. You could also probably remove the control tag mapping if you don't have any WebForms pages in your app.

   If you are deploying to IIS 6 you could get rid of the <system.webServer> section but you might want to leave it in in case you ever upgrade the server.
