You might want to e-mail Ace at Ni-wumpf on the attract mode stuff, it may just not use those, I don't have a ni-wumpf in mine and mine is buried/stored at the moment so couldn't check anyway. Ace was pretty helpful when I had some issues, he may have ideas on the other issues as well, doesn't hurt to ask.
On the multi-bonus lights, looking at the schematic it appears to show them all as one lamp, so they should all be just wired together. I would check continuity between all those first and make sure the sockets appear OK as well.
Not sure what to look for on the shoot again, that the backbox one is always lit is weird, maybe something not hooked up right when re-pinning?
