Need Help Confirming This Circuit Still Works After I Modified Some Components...

Alright so what I am doing is getting reed of any components that I do not need to make the Arduino Fio board smaller in size. I already hooked up the board, installed my program and it works as I need, but I also have many other things on the board that I am not using so I want to get reed of them.

These are the components/pins I do not need:
-Battery Port (located on far left side by edge)
-Charging Port (located on far left side by edge)
-Reset Button (located on far right side by edge)
-Reset LED (located on far right side by edge)
-pins A0-A7 on ATMEGA... chip
-pins D6-D13 on ATMEGA... chip

So I deleted those components on the schematic, however, I am not sure if I deleted something that was needed for the Arduino to still have basic function such as being programmed, being able to be charged via mini B usb etc.

I have attached the modified schematic (has less parts), then the original schematic.
