At this point we don’t automatically calculate the %complete planned. As a workaround you can create a custom field of type Text and insert there the %complete planned.

In order to see the planned finish date for a task vs the actual finish date, please set a baseline by going to menu Project-Set Baseline.

After this, if you encounter some delays on tasks, please change the Start/Finish dates in the Gantt Chart view. These dates will be the actual start and finish dates. The planned dates can be seen in the Baseline Start and Baseline Finish fields.
