Answer 1

As I see it there are mainly two types of components.

1. Control (Button, TextInput, TextArea etc)
2. Container (VGroup, HGroup, Accordian etc) With control components, you can set the properties and it gets reflected in design view of Flash Builder. Contains on the other hand can have layout logic and can accept drag/drop of other controls/containers. It depends on which kind of component you are trying to develop. In Flash Builder 4.5 you can see DataGrid supports direct connectivity and is more advanced. You can set the dataprovider and map the data to grid columns. For that kind of functionality, you will have to extend the design view extension.
