I agree on the filter system. They can be expensive, but they are a huge help. We installed one at my grandparents house to make the water a little more pleasant. They didn't have a sulphur problem, but there is a significant mineral content to their water. It tastes funny, it etches the glassware, it discolors laundry, and it leaves a pretty good scale on teeth. We did exactly as CZ recommends. A large scuba tank looking filter on the incoming line, and another countertop filter (this was before the ones that hook directly onto the faucet) in the kitchen.
I think they're a pretty good idea even if you have city water. We use a line filter at home, as well as a filter pitcher for cooking and drinking. Our water has a noticeable smell (it's not really bad, but it's there), but the filters take it out. The pitchers run about $10, and the filter cartridges will cost you maybe $20 a year. At the very least, get one of those to filter your drinking and cooking water. I think you can even get the horizontal tanks with the spigot on the front. They hold ~2 gallons, and you can put them in the fridge if you prefer chilled drinking water.
