Maytag Dryer - drum not turning

Hi
the drum has stopped turning in my Maytag Dryer (model no. pyet444azw).
I assume the belt is broken.
Three questions.
1: How do I actually open up the dryer - i.e. which side do I unscrew etc (top, front, left?)
2: Has anyone got a manual for this thing, to help change the belt?
3: I am in Vancouver. Do you know where I could buy a belt?
Thanks
Garrett
