No, the jumpers take care of that for you.
My Beta 50's do not have the metal jumper. When you say use regular wire, will some extra speaker wire work?
Do I actually put the bare copper in the bindings?
Yes. That's what people did before fancy plugs and the like became the style.
One approach is to get a few inches of some bare copper wire, say number 12 or 14, and use it. Less messy than stranded speaker wire for making jumpers.
