Help with portfolio

Hi –
I’m pretty new to Flash and could use some help. I want to make a portfolio. On the picture below you can see what the page should sort of look like. The navigation is supposed to be in the left corner and stays there. The grey box on the right should be a placeholder where all the content is being dislayed. My silhouette is being imported as a movie (well, several movies).
Can anyone give me some advice on how to start with that (e.g. what to put in a movieclip?)

Thanks alot for your help,
Franni from Germany
