You can format it in any thing your kernel will support. ext3 is fine.

Works fine for me. This may refer to the Neo1973, or to old bootloader 
versions.

Some cards don't work reliably at the default clock rate, so you may need a 
kernel command line switch adding to change it. You may need to change the 
uboot parameters for kernels >2MB, or use Qi which handles large kernels and 
boots faster.

Depends on what you're doing with it. 512MB is fine for most distros, but 2GB 
is probably more appropriate for debian or gentoo. You may want more space if 
you plan to use it for audio. video or maps.
