I'm About To Go Back To 'Access'... Help Me

Hello all ASP'ers, 
 I'm very familiar with .net code and data access as it is what I do for a living. However, what I don't do a lot is make my own web project from scratch. All our DB connections are handled through a DB class that we instansiate and use, quite easy. BTW, we hit an Oracle DB and code in C# in VS 2008 Team Developer.

Here's my (simple I hope) dilemma.

I'm using VS2008, C#, SQL server database. I put a text box and a button on the front page (of my web page) for users to enter their email address for a newsletter. I created the DB by right-mouse-clicking on my project icon in the Solution Explorer, add new item, then selected SQLServer Database, it and saved it. It now appears in the Solution Explorer. I've added the table and columns I need but for the life of me I cannot connect to it. I've seen TONS of connection string examples but I need help getting the proper syntax for my situation

I have not created a user ID or a password for the database.

What do I put in for the DataSource and the database?

I dragged the database icon into my code and got the local path wher it resides:
C:FilesWebProjects2008WbProjApp_DataNews.mdf

Here is the most common connection string I see for SQL Server:

SqlConnection Conn = new SqlConnection(" +
"Data Source=Your server name;" +                      <------ What goes here?
"database=Your Database Name;" +                     <------ What goes here?
"UID=UserID of the server;" +                               <------ Can I get rid of this?
"PWD=password of the server;");                         <------ Can I get rid of this?

I've done a different project using an Access DB and have that guy up on the web working great, I just can't get htis one connected and the data a' flowin'.

Please help, this is my personal website and I want to use SQL Server but I'm getting frustrated and just might go back to Access, aaaaggghhhhhhh...
Once I get past the Conn.Open(); in a try/catch I'll be good. I've got the rest of the data commands in place and ready to go. 
Here is a link to a visual to help you see what I'm doing, it's just a shot of my solution explorer.
