Abhishek,
First off, did you ever get the above issues with the Like and Subscribe buttons working? I missed responding to your questions, and hopefully you got it going.
As for the Fan module, I just went to your home page and I'm not seeing what you mention. In the bottom of the left sidebar, I see your custom FB image that links to your page and then the JFBCFan module which just starts off with "Find us on Facebook". If you're seeing something different, can you let us know where we should look and possibly attach an image of what you're seeing as well?
Thanks,
Alex
