Well, the verses in Seven Nation Army have a really bass-y tone, while the chorus part has that biting treble-y tone. So if you have a guitar with 5-way pickup switching (like a strat), I would suggest turning the tone fairly low for the neck pickup and turning it around 6 or 7 for the bridge pickup, then just switch pickups when you move from chorus to verse or vice versa.

For the solo you're gonna need sustain, so if you have an additional distortion pedal, that would help.

And I believe Jack White plays the song in open A (or E, I forget) tuning with a slide.
