Answer 1

If you install the Microsoft.Bcl.Async package, you get a few async-ready extension methods, including ones for HttpWebRequest.

Answer 2

Use TaskFactory.FromAsync to create a Task<Stream> from the BeginGetRequestStream/EndGetRequestStream methods. Then you can get rid of your OnGotWebRequest completely, and do the same thing for the response.

Note that currently you're calling EndGetResponse when a BeginGetRequestStream call completes, which is inappropriate to start with - you've got to call the EndFoo method to match the BeginFoo you originally called. Did you mean to call BeginGetResponse?
