Formatting an SDHC card

[datapusher]

I am running no2chems rom
I just got a class 6 4gb micro sdhc card
I am planning on running iGuidence on the sd card
do I need to format? i usually like to start off new media fresh and formated.
Which format do i use (NTSC, Fat, Fat32)
Will Pocket Mechanic do the job, or is there other program for ppc I need to use. I don't have a reader for my comp.

Tried searching but didn't find anything concrete on this issue.

Thanks
