Most of the stuff you listed that it won't compress is already 
compressed. I'd throw in rpms, debs, compressed tarballs, Ooo documents.

I'd not use the compression. I do use these devices, I have three, but I 
use them for transporting files, and if they're not alreay compressed, 
then creating a tarball directly to the drive works:
mount /dev/sdb2 /media/usbdisk
tar cjf /media/usbdisk/myhome.tar.bz2 ~
umount /dev/sdb2

Adjust to taste. use a GUI if you wish.

For compatibility with windows, use zip instead.
