The boot flag is used to indicate which partition of the disk to boot
from. The LBA flag is used to indicate logical block addressing, as
opposed to CHS (cylinder-head-sector).

You don't want to get rid of LBA.

If you're just doing regular data backups, you're right that you don't
need the boot flag. To remove it in GParted, right-click the partition,
click "Manage Flags", then uncheck "boot" (sorry, I don't know the
French localization for this).

sda5. That's the partition the ext3 filesystem is on. The "extended"
partition is just an artificial construct designed to allow more than 4
partitions on a drive. Incidentally, you could get rid of it since you
have only one partition. However, that would require reformatting.
