So if I understand it correctly, I will have to use one of the Zoom's stereo inputs (since I don't have studio monitors, I use headphones) and whenever I want to listen to Youtube, I will just stop playback in Reaper, minimize it, go to Youtube and raise the input level knob on my ZOOM?
You said you have a different setup, do you use Windows as well? May I ask you how do you do it? Because I've been also thinking about buying a new interface.
It surprised me that you need to have the drivers separate. But it makes sense. So on Mac you would use CoreAudio for everything or does it also need to be somehow separated?

Yes on a Mac CoreAudio for everything. There doesn't seem to be a problem with multiple apps sharing the audio output.
