How to upgrade the Active Directory in our environment from 2003 to 2008R2

Our topology consists of 7 Servers.

1 - Server 2003 SP2, GC/DC
1 - Server 2003 SP2, DC
1 - Server 2003 R2, DC, Exchange Server
1 - Server 2003 R2, Member Server
1 - Server 2003 SP2, File Server
1 - Server 2008 R2, Terminal Server
1 - Server 2008 R2, File Server

Our current forest level is 2000, and the domain level is 2003.  Is it save to say that I can just put a 2008 R2 cd in the GC/DC and run the forest prep and ad prep commands to upgrade the levels?  If there is anything else that we need to be aware of so we dont break the domain, that would be appreciated. Thanks.

Dependas.  Are you UPGRADING the domain to AD 2008 native mode or do you just want to add a 2008 R2 DC?  If you upgrade AD, then your 2003 DCs will no longer replicate with AD.  If you just prep the domain and add a 2008 R2 DC, that's fine.

I would, of course, run some diags first - DCDIAG and such to verify the AD is healthy.

I want to eventually turn the 2003 GC/DC to a 2008 R2 GC/DC but at this point i just wanted to upgrade the domain to support DFS that I am trying to get working on the two 2008 servers.  I cant get them to work properly together because I dont think the AD is supporting it.

Also, my forest level is 2000. Should I move that to 2003 right now?

If you're looking to support DFS-R you need 2003 R2 or later.

If you have no 2000 DCs and don't plan on ever making them, then I'd make the domain 2003 native.

Note you CANNOT upgrade 2003 DCs to 2008 R2 as there is no 32 to 64 bit upgrade path.  You CAN MIGRATE - but a Migration is NOT an upgrade.

Ok, so what would you say is the best way to migrate that 2003 GC/DC to to 2008? I can migrate the roles to a new 2008 GC/DC box, but I need to eventually get the 2008 box to work at the same IP address that the decomissioned 2003 box was at.  Also, what do should I be concerned with on the other DC's that are 2003 and 2003 R2 for the exchange server? Can those be DC's with the newly 2008?

Why?  Why do you need to keep the same IPs?  

So long as the mode of the domain is not higher than an existing DC, all DCs should be able to communicate with each other, assuming you have everything setup properly.

Well all of the workstations that are on the network are pointed to that DNS server which is the GC/DC for authentication. So it would be necessary I suppose in order for them to authenticate, right?
