Hi Greg,
The fields you refer to are system calculate fields.
To populate the baseline fields, you may select your project in the grid, then go to the Misc sub menu of the work plan, and click on Save as baseline.
This will allow you to later see baseline start dates/due dates, and also use the baseline and plan vs actual options in the Gantt view.
The status field shoud be overrideable. Perhpas you refer to State ? To change it, you may again select your project, and in the common submenu of the work plan click on Mark as (and whichever state you wish)
Best Regards.
