Seeing how troublesome our water heater ordeal just turned out to be, I've decided to compile a collection of tips for those who run int this problem in the future. With any luck, this post can get indexed by Google so that you can get all of this information in one place, as I had to read several different pages of info to get it. Anyways, here goes...
First and foremost, make sure that it isn't just condensation. This should be fairly easy to recognize, as condensation won't cause very much water. If there is a large growing puddle on the floor, it probably isn't condensation. If you've got carpet nearby that now goes "squish" when you walk on it, that's also a good sign that you've got real trouble on your hands. In our case, we could actually see the water running out form the base of the water heater tank.
Once you've determined that the water heater is in fact leaking, the first thing you want to do is shut off the cold water supply going into the tank. There should be two copper lines going into the tank. One supplies cold water and the other carries the heated water to various areas of your home. The cold water supply line will have a shutoff valve. Turn it clockwise and close it off completely. This will prevent the tank from filling up with more water as it is drained.
Next up, find the breaker and switch it off. If you've running a gas water heater, I'm not sure of the steps involved but I would assume that you need to shut off the supply of gas and blow out the pilot light at some point. Google for more instructions if you need to.
Next, go to the bathroom and flip on the hot water faucet in the tub and let it run. You may want to put the drain stopper in and save this hot water for later, as it may be the last hot water you'll have for a day or more. Get yourself a garden hose and connect it to the small drain plug at the base of the water heater unit. Run the other end to a bath tub or outside. Then open the drain and allow it to drain the tank as much as possible. If you find that there is no water coming out after you've opened the tank drain, you've probably got a ton of sediment crusting up the bottom of the tank. You can try taking a metal coat hanger or other rigid wire and sticking it into the tank drain to scrape some of the crud loose. Make sure you have a towel handy, so that you can catch the water if/when it starts to flow out. Then shut the valve, reattach the hose, open the valve and allow it to drain.
While the tank is draining, you should start mopping up as much of the water as you can. If your water heater sits on concrete, you can use a mop and some towels. A wet dry vacuum or a steam cleaner also works good at sucking up excess water. If you've got carpet near the heater that got wet, you're in for more work. First suck up as much water as you can. Then you'll need to pull up the carpet by the edges, and prop it up so that you can blow a fan between the carpet and the pad. This is the only way we were able to get our carpet pad to dry, as it is made of a foam material that soaks up moisture. It is also where mold is likely to grow if you leave it untreated. Your carpet should basically create a tent with air blowing through it and the pad.
Get as many fans blowing in the room as possible, and crack some windows to allow for more air flow. The best fans to use are the small snail-shell styles that sit close to the floor. This is what the professionals use, but you can find inexpensive ones at places like Wal-Mart being sold as shop fans. Some people suggest turning on the heater to promote evaporation, but I also read that this can promote mold growth, so I wouldn't recommend it. Cold air obviously won't help, but I'd leave it at room temperature.
Once you've taken care of the water on the floor, and you've drained the tank as much as possible, you should be calling for a plumber to replace the water heater. Within a day or two, the carpet should be dry and that moist smell should be subsiding. If it isn't, you may have to have the carpet professionally cleaned or replaced.
