That part (changing the /home directory to a different mount point) I 
know can be done as I did it a few weeks ago. I have lost the web 
reference to an article showing how to do it but you should find 
something if you google around. I think it went something like:

-  login as root
- init to single-user mode ( init 1)
- mount the new partition somewhere temporary
- copy all /home/* stuff to the new partition
- unmount the temporary partition and remount at /home
- init back to 5 or 3
- set up fstab so the new mountpoint is there on reboot

That may not be the exact sequence, but it was quite easy.
