Really, you don't *HAVE* to use anything new, if you don't want to. SQL Server 2008 is upward compatible with SQL Server 2000 in *almos* all regards. Any query that work with 2000 should work with 2008. You might find some minor connection string differences, but once connected you should be fine.

Don't get me wrong, there are some nice new features in 2008, and ENVENTUALLY you should learn about them. But you don't have to know them to get started.
