model organization and sketch parameters

[Anonymous]

I have a model that is composed of several components.  First of all should the sketches that are used to create the components(bodies) be stored at the top level of the model or should the be nested under the component ?  

Second, each the components share a similar shape, but each component differs by an external parameter.  As a simplified example consider a isosceles triangle as the basic shape but the angle of the apex varies based on what plane the component is in(I have several construction planes that are at different angles).  I was going to duplicated the sketch for each component and change the parameter in each copy.  My question, is there a way to do this without duplicating the sketches.  I hope my question is clear.  If not i can include a few pictures
