What accessories for Olympus C-60?

I've just purchased an Olympus C-60 6MB, my first digital camera. I
will mainly
use for casual pictures, but want to be able to crop and some close-ups

of smiling faces.

Consumer Reports suggests purchasing a second battery and larger media
(it comes
with 32MB xD-Picture Card and Li-12B Li-ion Rechargeable Battery).

I see there are lots of brands and sizes to choose. Can anyone make
a suggestion what brand/size to buy? Any other accessories really
useful?

Thanks in advance.
