Questions about my Bios chip, required equipment.

If anyone can briefly explain to me what the 8 pins do in general and why we hook them were we hook them on the Pi it would be greatly appreciated for learning purposes!

EXAMPLE:
Why connect 3 pins to the 3.3v if two are optional?
Should I disconnect the MBP battery before attempting this?

Thanks,

Ok, you can find my tutorial HERE which also has a video. That should explain everything you need to know and more. But as to why you need to hook what where... The Raspberry Pi has designated pin-out for the GPIO header. They correspond to the pins on any and every chip as long as they are connected properly. I briefly touch this in the tutorial as well.
Pin1 - CS/SS - Chip Select or Slave Select - Used to select the chip if more than one is present in the current connection.
Pin2 - SO/MISO - Slave Out or Master In Slave Out - Used to receive data from the chip.
Pin3 - WP - Write Protect - Used to protect the chip from writing when more than one chip is present in the current connection.
Pin4 - GND - Ground - Used as the negative power source.
Pin5 - SI/MOSI - Slave In or Master Out Slave In - Use to write to the chip.
Pin6 - CLK - Clock - Used to set the frequency or clock speed f the chip.
Pin7 - HOLD - Hold - Used to suspend serial input.
Pin8 - VCC - Voltage Common Collector - Used as the positive power source.

Any other questions please don't hesitate to ask.
