add these lines to your /etc/fstab:
/dev/sde1 /mount/point0 ext3 defaults 0 0
/dev/sdg1 /mount/point1 ext3 defaults 0 0
What this does:
specifies the device, mount point, filesystem, options (defaults in every distro I used is a good choice, or just use whatever /'s options are), the fifth field is used by the dump command, just leave it zero, and the sixth field is the fsck scan priority if you systems crash... unless you keep valuable data on these drives, its safe to leave it at zero (don't automatically check).
For more in-depth information consult "man /etc/fstab"
