The 1996 Camry was probably one of the best ones of that generation - long lifespans are not unusual for that series.
As far as maintenance - best bet is to follow the manufacturer's recommendation, Toyota's not the dealership. This information can be downloaded from Toyota's main website under the parts and service tab. Should be identical to the Factory Scheduled service booklet that comes with the vehicle (if you still have the original paperwork lying around).
The big ticket items that should be looked at are the timing belt and waterpump. Normally a 60K mile service interval - most due the timing chain, but forget to replace the waterpump. If it hasnt already been replaced, now is a good time to do so, before summer comes around. Nice to couple that replacement with a timing belt change, since basically all the same components have to come off to get at them anyway, just saves you extra labor charges.
Plugs, distributor cap, rotor, plug wires, check coil pack (basic ignition system tune-up). Drain and replace coolant (highly recommend Toyota Red - doesnt wear out the seals on the water pump). Drain and replace automatic transmission fluid (if applicable) with Dexron-III or similar. Might also be a good idea to flush the brake lines (brake fluid is highly hydrophilic, ie. "water loving", something that should be done every other year under normal conditions - especially if car is equipped with ABS (valves corrode rapidly if water is present)).
Other than that - air filter, oil and oil filter, and a whole host of inspections of chassis and driveline bits. Should be good for some time still.
