Tensioner and Pulley Kit. Transmission fluid and filter. Valve cover/valve cover gasket.
Full trans service is usually done at 100k (Filter, pan, mech seals, new fluid). Fluid changes I've heard between every 40-60k miles.
I would 100% do your accessory belt and tensioner/pulleys soon. It's not expensive but breaking one can leave you spending thousands. Ask me how I know....
Also the valve covers on these cars are known to leak. I wouldn't change it until you need to put get on there with a flashlight and look for oil seepage. Most start to fail around 80-90k miles.
