Web pages 2010

Question

I am new to working with C#.net 2010 professional version using asp.net programming. I do have a little experience using C#.net 2008 on a desktop application.

I have the following questions:

1. I am looking for good references that I can use to learn to write an application that has all code in contained in aspx, cs, and js files. I will be writing some new webpages that are suppose to be written similar to the existing ones. (Have the same look and feel.) There is a main internet web page that everyone logs on to by supplying the user name and password. From the main page, the user selects what webpage the want to work with.

2. I need to come up with a 'graphic representation' of what the new web page is suppose to look like. Is there some way using visual studio.net 2010 asp.net version where I can draw what the page would look like? If so, could you point me to a book and/or a link that I can use as a reference to learn how to draw what the web page will look like?
