I'd go to Satan and get about 3-4 quarts of new fluid. If you want to go all out, you can pick up a new tranny filter, (probably not totally necessary), and pan gasket.

If you bought the filter, drain the tranny fluid from underneath the car and drop the pan. Once you get that far, the filter should be right there facing you; it should only be held in with a couple bolts. Replace the filter, then replace the pan with the new gasket.

To flush the fluid, you'll need a section of plastic hose, a bucket, and a funnel.

There are two small lines that go to the radiator from the transmission; one is an oil feed, and the other is a return (I don't know which one is which). You'll want to remove the return line from the radiator, and replace it with the section of plastic hose. Direct the hose into the bucket. Place the funnel in the transmission fluid dipstick.

Start the car: tranny fluid should start flowing into the bucket. Begin adding new fluid through the funnel. Keep adding new fluid through the funnel until the stuff coming out of the hose no longer looks cloudy.

It helps to have a friend with you, because you'll want to shut off the car immediately after that point.

That's the gist of it. It's a fairly straightforward procedure; especially if you don't have to climb under the car and replace the filter. You should be able to get by with the basic hand tools and a few hours on a Saturday afternoon.
