Start by reading http://jakarta.apache.org/avalon/developing/decomposing.html
if you have not done so yet. It has a discussion on what a component is and 
isn't.

Just like you, I tended to make everything a Component when I started with
Avalon (getting there from an EJB background). 

Rule of thumb: A Component is not a domain object.

You seem to have a COM / C++
background - have you worked with DirectX? The IDirectDraw interface is a 
Component. The IDirectDrawSurface isn't. (As I see it, anyway.)

If you have EJB experience, I'd say a Component is roughly equal to a
Stateless Session Bean. It is *not* an Entity Bean.
