This will be a good start for information and pointers to the various aspects of operation:

I don’t use any of the WD apps for access within my local network, I just map the drive into my computers’ file systems; see p23 of the user manual.
All device setup can be done via the web browser-based Dashboard, using a UI built in to the device. Again, the user manual describes this.
I find the multitude of apps that WD encourage you to download to be confusing, and largely unnecessary. SmartWare backup might be the only one I’d use, if I didn’t already have an established backup system.
