If I run cable from the battery, through a circuit breaker and up to my amp distribution block, do i have to put a fuse in between the distribution block and the amps, or use a fused distribution block, or neither?

Neathier, you'll be fine with just a circuit breaker inline before amps.
Ain't no 1/2 steppin' -

An example: Say you have a 1000 watt 5-channel in-boat amp that requires a 100A fuse be installed in front of it. Then for the tower speakers you have a 200 watt amp that requires a 30A fuse be installed in front of it. If you put in a 150A-200A fuse right at the battery and someting funny happens to the tower amp, it might go into flames, as there is a real chance the main fuse will not pop.
If your amps have no built in fuses, you want to install a fuse at the battery to protect the power wiring in the event of a short-circuit, (to prevent the boat from burning down) PLUS the appropriate-sized fuses after the distribution block to protect the individual amps in the event of speaker wire shorts, reverse polarity, etc.
If your amps have built-in fuses, disregard the example above.
