High level steps:

prep your forest for 2008 R2  I'm guessing your 2003 box is 32 bit so use adprep32
install the 2008 R2 member server (can be done before the prep too)
use dcpromo to promote the box
make the box a global catalog (does it by default in the 2008 R2 dcpromo process)
if you have DNS on your 2003 box install it on the 2008 R2 box
At that point you have a fully functional 2008 DC
Transfer FSMO roles to 2008 box
Point clients (static and DHCP) to the new box for DNS services.
once all your 2003 DCs are demoted you can raise the functional level.

There is a lot of great info on this subject already so I won't rewrite the book.

I also really like two blog entries by MVPs on the upgrade.  One is from Meinolf the other from Sander.

Are your AD admin tools letting you down?

Managing Active Directory can get complicated.  Often, the native tools for managing AD are just not up to the task.  The largest Active Directory installations in the world have relied on one tool to manage their day-to-day administration tasks: Hyena. Start your trial today.

No, it cannot be a DC until you run ADPREP on the existing domain and prepare it for a 2008 R2 DC.

mkline has already posted some links, my favorite is:
