Besides removing the mount points from fstab, what other steps would I need to take. I want to reuse the mount points to mount a NFS volumes to.

It depends, after removing from /etc/fstab, umount each file system using:

umount /mount_point

To be able to umount it, you must stop all process accessing that mount point, or you will get "device or resource busy". A reboot is the sudden and easy way.

after you unmount the filesystem just issue the iscsiadm command with the --logout parameter.

This will remove the device in /dev

Something similar to this...
iscsiadm --mode node --targetname iqn.1984-01.com.something:group-0:222:targetname --portal 192.168.10.2:3260 --logout
