I would suggest putting volume and wah pedals first. Distortion second. And phasers, flangers, chorus, and delays last. This is the configuration I prefer, but don't be afraid to switch things up. You'll get different sounds depending on what order you place them in. I use a Dunlop Juice box to power my board and it hasn't let me down yet...I have 7 pedals on it and the thing doesn't even get warm after 2 hours of gigging. Try it out.
