honestly? i dont have a clue how to use the manual focus on my sd1000 (only have it in chdk)
For those pics i just set it in manual mode, set the shutter speed override to 1/100,000th of a second (i know it wont go that high but that was to achieve the highest speed possible) and set the metering mode or w/e to macro.
the SD1000 doesnt have and ajustable flash output. This was just autofocus and alot of shots lol
