Given the confusion that seems to be going on do something like
this:
   mkdir /newhome
Add an fstab line something like this for the new disk.

   /dev/hdb1    /newhome             ext3    defaults        1 2

Now make sure that /home and /newhome are as expected.
i.e. make sure you have not removed files you do not
have copies of.
   
Next swap the rename the old /home dir to /oldhome or some such thing.
i.e. edit fstab to mount the old home space as /oldhome and the 
new as /newhome.

 i.e. do not mount /home as /home yet.  Let it be an empty dir
 or mount point.  Just mount /oldhome and /newhome

If you have fstab lines like this you may find that you 
can be confused about the physical device under things.

   LABEL=/home  /home   ext3    defaults        1 2

The above is important because a partition label can cause confusion.

You can orient yourself with tricks like "df ."

    $ cd /home
    $ df .
    Filesystem           1K-blocks      Used Available Use% Mounted on
    /dev/hda5             10713248    247936   9921096   3% /home

When you have /oldhome and /newhome clearly identified and labeled
then fix things so that /newhome is /home.  Check and verify...
perhaps with:

    $ diff -d /home /oldhome

When all is right in /home remove /oldhome you can recover the space.
If it is an isolated partition removing the files will not 'add space'
to /.

If you have multiple users.  You can consider keeping the /oldhome
partition as say /homeA and move some users there.  I happen
to have collected  a lot of stuff in my 'src' dir.  In the past 
I have made a link to another partition for bloat stuff like that.
Same for system documentation...  "df -s /* " might give you
a good choice of stuff to move.   Recall that some things
are best located in the / files system.

The goal of the above is to be cautious so the recovery CD
lets you recover by simply undoing a single step.
