very sorry to disappoint you about the adobe. My adobe is from my gf. She works as a graphic designer so the company installs one in her laptop. everytime i need to use it I just use her laptop. :)
Frankly, finepix viewer is one of the worst imaging software around, so don't bother to install it.
For the energizer, i use the rechargable ones. for one straight long use without flash, I can go about 2 hours. But frankly, the non-rechargable ones are better. I've tried using those which are silver colored, top of the line. I went for 3 hours. Note that all these are without using flash at daytime.
To focus, you will have to press the shutter halfway until you hear the "bee-beep" sound. Only then you should press all the way down. Do this everytime you take pix, not just for macro. Your pic will turn out sharper. :)
I hope these help. Have fun trying! :D
