Thats pretty much what I do to. Stabilizer in the tank, drive around for a while so that it works its way into the rest of the fuel system. It's also a good idea to make sure you store the car with a full tank, you then have less headspace in the tank for moisture to form in, which will not only keep water out of the gas but cut down on rust forming in the tank itself. I would recommend a good battery maintainer, a trickle charger with an automatic overload protection. This way when the battery reaches full charge the maintainer shuts off, then comes back on again when the charge level drops. I have a small one thats actually mounted in the engine bay. I just run an extension cord up through the front valence and plug her in, has kept my battery in top shape for years.
Besides the other items mentioned I would suggest that if you know you are not going to drive the car at all over the cold months to get it up on blocks. This will prevent the tires from flat spotting if the car sits for a long time. If you don't do this make sure you take the car out at least a few times over the winter just to get the tires rolling and the spot they rested on moved. Also, some people like to throw packs of silica gel into the footwells, can keep moisture and later musty odors from forming. Of course make sure the antifreeze is fresh and at the right concentration, and the point Dave made about the E-brake is excellent, release that thing and block the wheels. Nothing worse than getting excited about that first springtime drive and not being able to disengage the parking brake.
