If you followed the Prequisites section of the how-to on deploying for windows, you should now have a folder with the Mendix server files needed to run your application. It is the path to these.
The project and log path etc. are also the paths to the folder you created in the Mendix server folder, not the project path you use for the modeler.
So you should have some folder which I'll for the purpose of example call 'Server'. If you followed the how-to, you should have subfolders in here called Application, Log and Mendix. These are the paths you need.
Application root URL: This should be the public url of your application where users will find the application, for example: http://backorder.mycompany.com/
