The importance of Photoshop in Flash

I am pretty new to flash and REALLY new to photoshop but when I check out the great flash sites out there (I am sure you can all name tons :slight_smile: ) it seems like although the flash animation is smooth the things that seperate them from all the other sites is their great skill in Photoshop or some other Illustrator.

Because of this I have decided to mainly focus on the visual aspect of my upcoming site rather than things like Action Script.

Do I have the right proities as a begginer? I know the basics of Flash well but if anyone things I should focus on a different aspect please let me know.
