Welcome to GenVibe!
There's lots of maintenance info in the Maintenance and Care section of the board.
Off the top of my head, you'll want to check/replace the following:
Brake Pads & Shoes
Engine oil
Transmission Fluid
Brake Fluid
Radiator Coolant
Power Steering Fluid
Engine Air Filter
Cabin Air Filter
EDIT:
Positive Crankcase Ventilation Valve (PCV)
Mass Airflow Sensor (clean)
Throttle Body (clean)
Idle Air Control Valve (IACV) (clean)
Oil Control Valve & Filter (OCV)(clean, though some replace the filter)
You may consider changing the Intake manifold gasket as they tend to get leaky and cause rough idle- you'll have the throttle body off, so you can clean it and the IACV in the same session.
That should keep you busy for a while...
