Answer 1

For this you use Twitter's OAuth authentication framework. It's used so that users don't have to directly enter their user + password into your site. (I assume you know how the front-end to that works already.)

You can use this little example to use OAuth from .NET - it is built for ASP.NET. (The demo the guy provides is My Tweeple.)
