import project map into points estimator

how do I bring my proposed mission into the points estimator?

and how can I change units from meters to feet

Import the KML file into Map Pilot Pro by going to the File Manager screen and hit the Import button. Then use that shape to design your flight. The point estimate is in the top left pane. 

Changing the units in the app can be done in the Settings and it can be done on Maps Made Easy following the directions here:
