Dear Vinayak,
Ans for Question A: Yes. We have prerequest for to be deploy to the fiori launchpad. Please refer below link
Ans for Question B: index.html is not mandatory to upload with BSP file. But, it's depends on your component.js. You deploy complete project into BSP file and test it from there itself. If index.html file is not there in BSP file, you cant test the application.
Regards,
Ram
