Watch the Jimmy Page online guitar lesson by Jeff McErlain from Kings of Tone
Page doesn't use many pedals, in the old days he would use a Tonebender fuzz pedal that you can hear all over Led Zeppelin I, a wah pedal, and that's basically it! Pretty simple. His tone is not too difficult to get because it's so basic. Any decent overdrive and wah pedal will do, and for more spacey stuff like Dazed and Confused, a delay pedal. The order should be guitar-wah-overdrive-delay. This is a great basic rock setup that will cover most players.
