What effects does Johnny Greenwood use in the Radiohead song Just?

Our band is to perform this song live in the not to distant future and I'm trying to gather up all the correct guitar effects. Admittedly, over the past few years I haven't worked much with effects pedals outside of a practice amp, so this is foreign territory to me. The verse sounds clean with some bluesy effect in places, the chorus uses some form of distortion, and the Whammy Pedal pedal comes into play near the end. I know this much. The bridge is harder to figure out. (2:08) Obviously it takes a good degree of experimenting to get things sounding good, but of course pedals aren't cheap so I'd like to get some rough idea of what's going to sound correct before investing.
