Sugoi, that is the exact same problem on the exact same hose I had, luckily i caught it before it burst. You can see all the threads in that area were breaking, the hose has lost its 'texture' there and is bulging outward. Everyone should definitely replace those 2 'Dos Amigos' hoses.
As for the little hoses, one of the little 'bypass' hoses was leaking when I bought the car, I was lucky to make it home to Ohio from New York with it. There was no coolant left in the reservoir but fortunately the radiator was still full. When I replaced my hoses many of the smaller ones, including the oil cooler hoses would 'crackle' when twisted. I really recommend replacing all of them.
It's a DIY job if you have a good lift, some silicone lube and a large variety of pliers, otherwise leave it to the pros.
