Sorry I didn't mention, but you may have gathered anyway, it is a GM 350 Throttle Body Injected motor.
In addition to changing the engine oil and transmission fluid, I would replace the raw water pump impeller ($30) and fuel filter, unless you know they are new. Other basic maintenance items like cap and rotor, plugs, wires, etc. are up to you, but they can prevent you from being stranded and ruining a nice day on the lake.
