How do I setup a Windows Web Server 2008 R2 in a 2003 AD?

I'm what I guess you might call an accidental sys admin.  I don't have the training, and the guy who used to do this left last month, so I'm it.

Before he left, he requisitioned a new Windows Web Server 2008 R2, which just arrived today.  So, I've got to put it into the rack and get it joined to our domain.  We're using a Windows 2003 R2 Active Directory.  Naturally, I want this join this new server to our domain as a member server, but I've never set up a server before, so what steps do I have to do, to get this up and running?

Step 1: Follow instructions here to join the domain.

Step 2: Add "Application Server" Role from the "Server Manager". (See "How do I open Server Manager?" section near bottom of the page if you don't know where to find it.)

Is the Application Server Role automatically in place, with Windows Web Server 2008 R2, or do I have to install/enable it?

It's not enabled by default because not everyone would need web server running there. You have to enable it yourself. In fact if you want to join the server to a domain, you're advised to join the domain before enabling the roles so they could be properly configured.
