Yeah, you'll need to download the Secrets

I don't know if I have Flash installed- how do I find out?
No idea. Probably go to a site with a Flash element and see if it loads. Really, though, you should uninstall it. Unless you play a lot of Flash games, there's zero reason to have it anymore, and even the games can be played directly on your computer (instead of in a browser) with the Flash Projector.
Click2Flash is in the Safari Extensions gallery on Apple.com.
