Other than charging/ replacing the battery, checking fluid levels should be all that you need to do. If the car starts and continues to run, thank your lucky stars. Before driving it make certain that your brakes work, start out slow and if they work AND don't bind up, consider yourself very lucky.
After you have the car running to your satisfaction, you might want to change engine oil, oil filter, gas filter, and at least brake fluid (brake fluid should be changed every few years, but no one does it, however after sitting 2 years even I'd do it). Check the antifreeze to see if it will handle your locale.
