Short term build for a noob

I have recently bought all the bits to put together a retro radio for xmas. I am looking at boxing a pi, usb hub, justboomDAC, 7" touchscreen and a scrolling touchscreen into an old roberts radio (o yeah and some speakers!)

I am getting around the UI and struggling a little with the DAC output (another post), screen will arrive this week and I should be able to set up my out of the box test rig. I want to output the UI to the 7" screen when I can have success with the plugin installation, but also push the scrolling output to a small ticker tape display - is this possible and does anyone have much of a guide?
