Pi 3 questions

[skootx]

I'm planning a build with the following components:

Pi 3
HifiBerry Digi+
1 TB USB Hard drive with powered USB port
This will run out to a DAC/amp combo

Can I use Bluetooth to control Runeaudio from my phone?
Does Runeaudio support the official Pi 7" touchscreen?
How do I need to format the USB hard drive (file structure, folder hierarchy) and my music?

I'm planning similar unit. I read you should not have HDD and DAC both on USB. Do you have a concern here?
