1. I have a arduino nano board & made a small project on it. Its running succesfully.
2. Now i want to go to program 100 more MCU and make own board which is customized and has MCU on it?
3. How can i program MCU alone on my customized board. I dont need any FTDI ic or usb port on my board.

4. Also I dont need external crystal? How I can do change in arduino programming so that Atmega uses its internal oscillator only.

You can program the IC directly with a programming interface using the ISP pins: MISO, MOSI, SCK and Reset.
The on chip oscillator is selected using one of the fuse bits on the chip, this can be changed most easily from AVR studio programming interface. (Where you can also program the firmware). Though I do not know how you go about "flashing" multiple chips at once. I guess there will be more information on this on MicroChip's website and the various programmers.
