Your first item about the Picasa I don't know about.  But that camera is 
in all probability, a usb storage device, in other words, 

modprobe usb_storage, then
mount -t vfat /dev/sda1 /media/camera

and you should then be able to inspect the contents of the memory in the 
camera just as if it was a real msdos or similar clone fat file system.

One caveat though, if moving pictures from the camera to the computers 
hard drive, and since this is a fat system complete with the fat systems 
bugs, always start at the bottom of the listing.  If you start from the 
top, you may run into one of msdos's nastier bugs and lose all the 
pictures after the first 8 you just moved.  Been there, done that, lost 
the rest of the wedding shots, and had to format the card, which had gone 
read-only.
