As long as everything'* full, you're good to go to start the car.
Fire it up and check for leaks around the t-stat housing and also at either end of the radiator hose. It won't hurt to climb under the car to validate you have the pet **** completely turned off, either.
Once you start the car open the bleeder vent on top of the t-stat housing. Once fluid oozes out from it, close it. That will ensure you have removed all the air from the system.
The fluid level will drop in the car once the engine reaches operating temp (thermostat opening). Add coolant to the overflow jug to bring the level back to the normal range.
