2003 AD Best Practice questions

Here are two sections from a 2000 AD best practice article. Does
anyone
know if they still apply to 2003 AD?

"Make sure no single site is directly connected to more than 20 other
sites.

This condition can occur in large hub-and-spoke deployments where most
sites are branch sites that communicate with a centralized hub site. If
this condition exists and there are more than 20 site links from the
hub
site to branch sites, the hub site can be divided into multiple sites
to
provide additional bridgehead servers to handle the replication volume.
In a site, a single bridgehead server is active per domain. If the site
has more than 20 site links, the bridgehead servers can become
overloaded."

"Placing Global Catalog Servers

A global catalog server is required for logon to native-mode Active
Directory domains. To eliminate the need to contact a global catalog
server in a distant site for logons and for forest-wide searches,
designate at least one domain controller per site as a global catalog.

Best practice design dictates that half of all domain controllers in
the
site be global catalogs, with at least two global catalogs if your site
has multiple domain controllers. If you use the single, global domain
model, plan for all domain controllers for the global domain to also be
global catalog servers. Because the forest root domain is very small,
making all domain controllers global catalogs requires very little
additional resources."

(I just need confirmation that I understand this. In a single domain
one root AD structure ALL domain controllers should be GC's?)
