SAP Design Studio SDK Editing

Hi,

I am an SAP BIBO consultant. One month before I started using Design Studio 1.2.

1. Is there any document that will help in BIAL coding???.
2. Can anyone please show me from the scratch how I can edit the existing standard components in the Design Studio through SDK. I have tried up the addition of Custom components(Colored Box, Google Maps) in Design Studio. That worked fine. But my issue in modifying or editing existing components. How I can import those standard components to Eclipse and how to start editing???
3. Also one more thing, please show me from where I can download the UI Development Kit (SAP UI5) for Design Studio 1.2. and how to install the same.

I am using,

Eclipse Helios

JDK 1.6

Please help me in this........

Regards,
