Chaining?

Okay, I just got a Dunlop Original Wah, and i have a DigiTech MetalMaster.
I plan on using both, but which goes first?
Also, it's going to a Peavey Rage 158 if that helps any...

the metal master would be my guess

I generally place my Wah pedal before any distortion (or really any other effects. It's the first pedal in my chain). My reason being, when I hit the overdrive, I don't want the Wah sound on top of the overdrive, I want it under it to give it that smoking hot sound, if you get what I mean. Placing it afterwards will give the Wah a "cleaner" sound. Maybe that's not the best way to describe it, but try it out and you'll see what I mean.

I would put the wah before the distortion as well.

yeah, and thanks a bunch guys, it sounds great!

And now a problem has arisen:
The switch to toggle on and off is moody, and it has to be forced to go off and on, what now?
