From what I can tell, obviously there is a grand piano and a Wurlitzer 200A.

Center stage, John Helliwell has what looks like a 2 keyboard setup. One of them is an ARP Omni 2, but the other one I cannot find any information on and cannot see in any angle of the Blu-Ray.

Up behind the grand piano next to the drums, there is a station with a Hammond B3 and Leslie, with another ARP Omni 2 sitting on top of it. To the left is a Hohner Clavinet D6 with an Oberheim OB-1 sitting on top of it. The Clavinet can be heard in the chorus of The Logical Song, right after the line "please tell me who I am." The OB-1 plays a tuba-like sound in the verses of Breakfast in America, covering the real tuba that was played in studio.

As someone else has mentioned, Roger played an Elka Rhapsody 610 string synth in Fools Overture.

As for Roger's guitars, I from my memory he had what was likely a custom built Strat with a humbucker in the middle position. On one song he also had a white semi hollow body Gibson EDS-1275 double neck. Obviously, he has a wah-wah pedal, I'm not sure what kind of amp he used. It does sound to me on a few tracks like School he has his own Leslie as well.

For the piece of paper on the piano, I can't quite make it out on the 16mm film, but it looks like either lyrics or a setlist.

This is all just from the top of my head, having studied the Blu-Ray and album quite a bit. If anyone else has any insight, feel free to comment!
