If you are getting the joint tight when it’s clamped and the top is reasonably flat, go ahead and glue it up. Just make sure the joint is also tight when you look up from underneath. You can add the keys after the glue sets up if the clamping pressure to close the joint wasn’t too high.
Final flattening of the top side can be when you plane the keys flush.
You might want to put wax paper or cling wrap or even paper between the top and the leg assemblies so they don’t become fused.
