LED or LCD screen for camera/flash control project

Crossroads

I think a 4 line display would do the trick however I would like it to be red as im wanting to use it a night so red is best for the eyes. Do you know any other sites that may sell them in the UK if possible?
Im still confused on the interface types available. You said serial and others I’ve seen i think are parallel. Is one easier to work with than the other?
Is setting a menu simple? any example code you can point me at please. Im guessing the way you write the code depends on the interface type?

Thanks
