No.  If you just set your second board to toggle the I/O pin as fast
as it can, then that will probably be fine.

Yep.

Yes - it shouldn't be hard.

Regarding a series resistor - you shouldn't need one.

If you can't recover your fuse settings, you can send the board back
to me and I'll take a crack at it.  Worst case, I replace your
ATmega128.
