The kits I am putting together for the FEZ classes I am teaching use the component shield and a variety of Input and Output bricks. I am using a Pololu RP5 Expansion plate (http://www.pololu.com/catalog/product/1530) to mount and organize the components. This makes it easy to organize the components and keep them from wandering all over the desk.
Mount the Serial LCD using standoffs and mount all of the necessary bricks with a single machine screw. Use stick-on rubber feet on the bottom. I routed all of the cables so that they come out the top, underneath the LCD. Labeling the end of each cable would be a good idea.
