I change my antifreeze every year. I've usually changed the thermostat when I replace hoses... every 3-4 years. Your mileage may vary.

I usually follow the recommendations for the coolant type before I change it. As far as the T-stat is concerned (takes a deep breath) I usually wait until there is a problem. Replacing it just to replace it, is not always helpful and there is no promise the new stat is any good.
