I am setting up 2 Soundstream ref 500s in my car. I am running a "0"gauge wire to the trunk and am splitting into 2 "4" gauge wires to the amps. My question is what size amp/circuit breaker should I be using on the "0" gauge wire off of the battery?

if it is a true 1/0 you can use a 300A at the battery, i always use 250 just to be on the safe side. At the D-blocks you can use 125. Again, i would use 100 to be on the safe side.

Can I use fuse breakers instead of fuses? I have one stinger 250 amp breaker that I am mounting as close as possible to the battery. I also have two 100 amp breakers that I was going to use off of the distro block to each amp. Is this ok or do I need actual fuse blocks.

You can use them but I wouldn't.
They call them "break"ers for a reason. They aren't nearly as reliable as fuses and when they fail, they tend to fail in the closed position. I personally would only ever use solid element fuses (MAXI, MIDI, ANL, AFS, etc).

AGU fuses (or any glass fuses) have two cups with a barrel of glass in between them. The only way to get them to stay together is to solder an element in one cup, put the glass barrel on, thread the element through the other end cup and solder it on. Now instead of your electrical connections being made by the conductive element, it's being made by a solder joint of a bi-metal end cup. Often, the fuse will get hot and the element will melt off the solder point but then fall and make contact with the cup again. That leads to poor current transfer and intermittent cutting out of the device.
In a solid element fuse like an ANL, MAXI, or AFS the element is stamped out of one piece of metal and encased in the plastic cover. The contacts for the fuse are the same piece of metal that the fuse element is constructed from. When an ANL fuse fails, the element itself breaks inside the plastic case and has nothing to short out to.
Breakers are a mechanical device that in most cases have a set of contacts and an arm that is made of two types of metal. As an over current situation occurs, the arm starts to heat up and one metal expands faster than the other and the arm starts to bend or "trip". (There are different kinds of breakers but these are the most common in car audio because of their low cost) The biggest issue with breakers is that they need to be exercised regularly to prevent corrosion build up. Even so called "sealed" breakers will corrode over time in the automotive environment. In the worst case, an over current situation occurs several times but it's not bad enough to trip the breaker, just add to the corrosion at the contacts. Then when the "too large" load happens, the contacts solder themselves closed and keep passing current when they shouldn't be.
When breakers fail, they tend to fail in the closed position about 30% of the time.
When fuses fail, they fail in the closed position less than 1% of the time.
