The Active Directory Migration Guide (ADMT) is going to be a tool you will want to investigate.  There is a white paper to go along with that too

Depending on your needs and budget third party tools may also help.  Quest makes a good migration tool also (not cheap)

Thanks

this is the ADMT(active directory migration tool):
http://www.microsoft.com/downloads/details.aspx?familyid=6f86937b-533a-466d-a8e8-aff85ad3d212&displaylang=en

ADMT includes wizards that automate common migration tasks, such as copying users, groups, and service accounts; moving computers; migrating trusts; and performing security translation. ADMT is available on the Windows Server 2003 operating system CD, in the Admigration.msi file in the \i386\admt directory. You can perform ADMT tasks by using the ADMT console, by using a command-line procedure, or by using a script. When running ADMT from the command line, you can use an option file to specify command-line options.

GPOs can be handled by GPMC

Lots of good info in that white paper including migration tables.
On another note when you go from 2003 to 2008 you also get group policy preferences (GPP) so you may want to redo some of your policies (login scripts for example) to take advantage of GPP.
Thanks
