Raising domain to 2008 Forest mode, will that still allow Windows 2000 PCs?

Will be adding domain controllers running Windows 2008 and upgrading domain and forest modes to 2008 level, wanted to know if there are any special security changes to allow my existing Windows 2000 machines to still be part of the domain?

I found info on the forest / domain modes , however didn't find an answer about Windows 2000 client support.

Please include a link if possible.

You can have any client type you want in the Domain, just be aware that Windows 2000 does not support Group Policy Preferences, so you won't be able to use that functionality. The Forest and Domain functional levels limit the OS you can have on your Domain Controllers only. It doesn't affect what OS Member Servers and Workstations can use.

Yes as long as you are running SP4 you are ok; there can be issues with NT and 2008 (NT 4.0 Compatible Encryption)

The main thing to note is that 2000 is no longer officially supported by Microsoft.

Windows 2000 server and Pro editions are still allowed to be connected to a Windows 2008 Server domain functional level without issues but a Windows 2000 Server can no longer be a Domain Controller. Windows 2003 server will not be allowed to a domain controller either.
