If i understand correctly, i can use the arduino ide, and the USBtinyISP AVR Programmer Kit from adafruit using the 6pin isp header to program bootloader on chip..
Arduino ide> choose board(Duemilanove,atmega328), choose usbtinyisp> burn bootloader...
The other method would be soldering headers on one inch of goodness board using ftdi and burn bootloader form there...???? Please clarify...just learning

I don't think using the ftdi and Arduino IDE will allow you to upload the bootloader directly. To use the ISP you will still need a reliable way to connect the 6 pins necessary to program as well as short the DTR pin to RST or use tweezers to SHORT the .1uF capacitor, FOR THE ENTIRE UPLOAD PROCESS! If using the USBtinyISP, then the light will remain red until the bootloader process is finished. You are correct in that selecting the board and bootloader in the Arduino IDE will allow you to burn the bootloader.
The FTDI headers will allow you to upload sketches with the IDE which is different than burning the bootloader. If you don't have a need to burn the bootloader, then using the FTDI is the way to go.
Hope this helps,

I just received the OneSquareInch and of course, I can't seem to upload sketches to it. I looked through this forum but didn't find the "answer". I am using a MacBook Pro running OSX 10.8, I have Arduino software 1.5.3, and I tried using both an Arduino UNO Rev.2 , and a TinyISP from Adafruit. All I can get so far is what appears to be a "reset" but no code uploads, and I get lots of error messages from the Arduino application. I have shorted the capacitor near the reset pin. I have the QneSquareInch hooked up to the 6 pin connector on the Uno, except that RESET is tied to pin 10 on the Arduino.
First I uploaded the ArduinoISP version 04m3 sketch to the Uno, then in the Arduino application I opened the Blink sketch, and selected Tools:Board:Duemilanove or Diciemila, Tools:Programmer:Arduino as ISP, and then File:Upload Using Programmer.
I get various errors depending on some seemingly random bits . . .
I also tried to "Burn Bootloader" but had no success with that either.
---> any suggestions anyone?
