Default How to customize status bar/notification bar on samsung galaxy ace duos S6802?

Hello everybody. I am new to XDA so forgive me if I posted this in the wrong section . I own a galaxy ace duos S6802 and after researching a bit ,I have now managed to install A- Droid ROM,the only one which was available.
Now, I want to customise the status bar by changing the colour,adding more toggles on the notification bar;And lowering its transparency.
Please can any body help me ??
Is there any app or do I have to flash somerhing????

Thank you
