I think, searching memory here, that you could get SELECT privileges to the job tables and grant them. However that might mean the person could only query.

As far as DTS, I'm not sure you can allow packages to be saved from the designers without SA. Maybe you could try creating a role in msdb and assigning permissions to syspackages and see. I don't have an instance to test, but I would start there. The permissions structure was more manipulable in earlier versions, but I'm not sure if it was 2000 that hardened this, or 2005.

However, Jeff might be right here. There were few fine grained controls in 2000.
