Front and side: Blow in. Top and back: Blow out.

This is the "normal" setup for most.

Front Fans: In
Side Fans: In
Top Fans: Out
Rear Fans: Out

Not all system combinations like this setup so sometimes experimentation is called for.
The idea is to have a smooth flow of cool air going past the hot spots in your case.

Here is a good OC FAQ on the subject.

It depends alot on the shap and orientation of the case to how the fans should be but in general.

2 X 80 @ front are intake
1 X 80 @ side are intake
1 X 80 @ Top are Outtake
1X 120 @ Back as outtake
