If you haven't replaced the other hoses already, I'd do it, if one is rotten and aged enough to blow, the others won't be far behind. I learnt that lesson the hard way.
Before ripping the water pump off, remove your timing covers and either pressure test your cooling system or run your engine up till it gets to operating temp, on the underside of the water pump, out towards its drive pulley there should be a small hole about 1/4 inch in size.... Maybe a little smaller, this is there so that coolant can escape from around the bearing if the shaft seal has failed and tends to be the most common cause of water pump leakage.
Sounds like your getting pretty close to finding your leak, keep at it, you'll find that sucker eventually.
