Migrate SQL 2000 to SQL 2008

Hi,
  My company needs to migrate SQL 2000 to SQL 2008.  The SQL 2000 server is running on Windows 2000 server and SQL 2008 does not support Windows 2000 server, so we can't upgrade it to SQL 2008.  Also, double upgrade (SQL 2000->SQL 2005->SQL 2008) is not an option, because we have a very very short time frame.

  The only option I can think of is manually copy everything from SQL 2000 to SQL 2008.  This is ok for tables, views, stored procedures, and functions, but how about triggers, DTS packages, and jobs?

  Is there a good tool out there can copy triggers, DTS packages, and jobs?  Or can somebody recommend another way to migrate SQL 2000 to SQL 2008?

Thanks,
Wei
