Then go on to one of the signature phrases of the song:

A-|--6-6-4----6-6-7----2-4-6-------------------------| 
E-|--4-4------4-4-5----0-2-4-------------------------| 
 
At other places, instead of ending with the picked notes, this phrase 
can also end with a descending series of power chords: A5, F#5, E5  
 
Pretty much the rest of the song just mixes those phrases in different 
ways, and since it would take me a year to say specifically where 
everything goes, I'll let you figure that out. 
 
The really short chords in the middle of the song that get muted really 
fast after being struck I think have the following formations: 
 
   E       B       A 
======  ======  ======       Right offhand I don't 
xx999x  xx987x  xx765x       remember the order, though. 
 
 
As for the solo near the end, I fear that I might be terribly butchering 
Page's beautiful solo, but here is a rough estimate of it:
