What type of maintenance should I be gettinf on my car?

I drive a 2 year old Ford Focus, with 37,000 miles on it. Other than my basic oil changes that I've been getting, what type of maintanence should I have done at my next appointment? I don't know hardly anything about cars, so I don't want to go to the shop and get the run around. All that I know, is it should be time for some type of tune up or maintenance.

Fords usually come with a maintenance booklet in addition to the recommendations in the Owners Manual. There's precious little to do on a vehicle with just 37,000 miles - besides visual inspections of brakes, exhaust and such - it MAY be time for a fuel filter or air filter. My Fords don't require spark plugs or transmission fluid changes until 100,000 miles (although I do it earlier than that) and first cooling system service at 5 years.

Check the service manual to see what Ford recommends.
