Additionally I came to know that the 6 extra pins for ESP12E/F can be used to add SD card. Could anyone please put some light on this aspect as well. In this way I can save 4 IOs.

Those are used for the program flash. Not to be use for an SD card as well.

Can anyone refer me to a decent schematic that can be used for ESP12 breakout board?

Thanks,
