As it's connected to the metal housing, I guess this is an electrical earth - does it need to be connected up?

Does it need to be hooked up to function?  Most likely not.  It's pretty much up to you and whether or not your environment builds up a lot of static electricity.

And what does happen if there is a lot of static electricity build up?  Does the trackball get fried?

My guess would be no.

I think the ground wire is there to prevent the trackball/roller/plastic housing/metal mounting plate capacitor effect.

I'm guessing that they had a problem with people getting zapped on the metal mounting plate when they came up to, or were playing the game due to the trackball rollers building up a static charge.

I pulled the ground wires off of mine, and haven't had a problem.
