If you do not have fast fuses in 12V DC wire you may end up with loose and

Paul,
An in-line fuse close to the power source is always a good safety
precaution.
You are protecting the wire against a fault as well as the equipment on
the far end of that wire.
A 12 gauge wire will safely handle 25 amps - but it will not safely
handle the full 70 amp output of your wower
There's also a separate 6A fuse protecting the rest of the K3. Anything in
the power cable is strictly redundant. I don't use one.

I believe that the circuit breaker only protects the KPA3.
If you're running off battery, or other unprotected power-source, I
think you would really want an external fuse (as close to the power
source as possible, in case you get a short in the supply cable
somehow).

Yes, that is a circuit breaker on the K3 so a fuse probably is not
necessary. Of course there would certainly be nothing wrong with using
a fuse.

If you have the 74154 inputs connected to the K3 band data outputs,
nothing more should be required. The 74154 should adequately isolate
the inputs from whatever you have connected to the output side of the
decoder IC.
I don't even know if the capacitors are required (or desirable),

You could try increasing the VOX delay.
