Active Directory 2008 R2 Site Connection Configuration

I am trying to figure out the best setup for site connections in AD 2008 R2. I have 2 sites connected via fiber and each site has 2 DC's. What would be the best practice in setting up the site connections? Right now I have the following.

Site A
Server 1 has a connection to Site A Server 2
Server 2 has a connection to Site A Server 1 and Site B Server 1

Site B
Server 1 has a connection to Site A Server 2 and Site B Server 2
Server 2 has a connection to Site B Server 1

Router to Router VPN will connect the offices. Then what you need to do is setup Intersite Replication links in Active Directory Sites and Services. Make sure that a DC in each Site is configured as a Global Catalog. This is important if users are accessing data from the other sites. The Global Catalog lists all the Objects for it's own sites but also a Partial Attriubute Set of the other sites, so this is very important.
Are sites in question sharing the same Active Directory DNS name space? If not make sure you setup Trusts in Active Directory Domains and Trusts.
If all sites are in the same Forest make sure you know which Server is holding the FSMO Roles. This is very important if the Server that is holding the Roles crashes.

Both sites are on the same network and are in the same domain. I have replication links setup in Sites and Services. Below is setup:

Site A
Server 1 has a connection to Site A Server 2
Server 2 has a connection to Site A Server 1 and Site B Server 1

Site B
Server 1 has a connection to Site A Server 2 and Site B Server 2
Server 2 has a connection to Site B Server 1  

All 4 DC's are Global Catalogs. Also, I know where the FSMO roles reside.

Everything looks as well from me. Just make sure you have the clients pointing to their local DNS servers
