That's basically it. The riff that's played when Dave Grohl sings
"And all i wanna do is have my mind erased..." can also be 
played as a full powerchord by just barring the same fret 
on the E (tuned to D) and A string.
You should be able to play the rest of the song from here.
I will try and work out the Wah-Wah solos.
Enjoy.
