Why don't you stick to stating the problem you want solved.
You proffer information which sounds like you are asking several

Usually, if you want a filesystem encrypted (especially the root filesystem)
then you have to select that at install time.
If you want to encrypt the /home partition, you can do it at install time
or you can do it later by first backing it up to some other media,
then running mkfs on the home partition using the right arguments 
(assuming the
kernel has that type FS modules), and then mount the new encrypted home
and tar out the backup to it (will likely involve providing the 
encryption key
either at mkfs time or at mount time). I have not done it before myself.

As far as how to install 12.04,
If I have nothing that I worry about losing (since /home is on another 
I would simply go ahead and do a fresh install of 12.04 on the existing 
system partition.
Just be sure you select an encrypted type of FS for it.
