Haven't tried the path palette before, so im not an expert. But from what I could figure out from playing around, it seems rather straight forward. You select an object and create a path for it and over a given number of frames it will travel from start to end.

Then you have some pitch, heading and roll settings, which seems useful if you are making a car or plane etc. And you can add more way points that you can place in the scene if you need a more advanced path and tell it to scale or rotate at a given way point.

So if you use the walk simulator and create a walk for La femme, she will walk as she move along the path.

Maybe you are after something more specific? :)
