Play Age of Mythology on top of what you've already read. Also, you can probably find the Illiad and the Odyssey online free and those are the main stories (not necessarily mythology mythology but they do feature the gods in action). Heads up on those: they can get a bit boring so you might also want to ThugNote or SparkNote parts of them.

well, that depends on what you want to know, there are many tales, such as Jason and the Argonauts, and The man in the minotaur maze

Read percy jackson story and movie when you finish reading it you will be a greek expert and watch the movie too
