Anyone notice that when you remove the 'fo' out of Sifo-Dyas, the name kinda sounds like sidious. Did Lucas do this on purpose. As for secret things in EpII, during the chase scene on coruscant, there are some TIE fighters chasing an X wing. They are very small and difficult to see, you may need to look on the Internet for an image, and it took me ages to find them. i think its just before Anakin is flying straight down and obi wan is saying 'Pull up Anakin, pull up'. I think there are also two Millenium Falcon type ships somewhere in the film. I remember that the two are on the left side of the screen and are both landed. it is in a scene where a red/pinkish transport ship is flying to land on Naboo, carring Padme, anakin and R2. You may need to find an image on the internet again as they are difficult to spot.
