If you really want to be cautious you can pull the distributor and prime the engine or when you have the plugs out (after ensuring that you can rotate the engine by hand) pull the coil wire and spin the engine over with the starter and check for oil pressure. Also make sure you have fuel in the bowl/s of the carb and sprinkle a little into the carb mouth so that the engine will fire right away. Make sure you have a good charged battery in the car as well.
Its not rocket science and relatively hard to screw up.
