what you need to know is you need to chose from the file menu Window→Actions and when the actions palette comes up on the right hand side should be an arrow that opens choices for that palette.
Chose Load Actions, then you navigate through to where those actions are. . .they will now be available inside the Actions Palette.
The basic way to use them is that when you have an image open in photoshop you select the action you want out of the list and press the play button on the bottom of the palette window.
That should get you started. Good luck.
