Why? I mean, CD-ROMs, being slower devices, should usually be used by
different hard disk controller than real hard drives.
IMHO you should make the other hard drive hdb, and leave the CD-ROM as it
is.

Set the jumpers of the drives so that your current drive is jumpered as
master (with a slave, if there's such setting) and the new (or used) drive
as a slave.
Boot your computer and setup (usually F2 or Alt-Esc) the cylinder / head /
sector per track settings (they are normally printed on the label of the
hard disk), or let the BIOS decide (AUTO feature, if supported by your
BIOS).
Linux can also detect second hard disk even when it is not set up in BIOS.

I have experience with new harddisks only, but:

If anything can go wrong, it does. Back up (recursively) the contents of
/etc, /root and /home.

You didn't specify your other configuration, but (IMHO) used hard disk may
be adequate for home use. Expectable mileage may be short, or then not.

Yes. Buy a new one. Manufacturer doesn't really matter.

You don't have to change lilo.config.
In this phase you should make your /etc/fstab to look somewhat like:

/                          hda        ext2      default     1 1
/mnt/usr               hdb1        ext2      default     1 1
/mnt/cd                hdc        iso9660 ro,user    1 1

After configuring /etc/fstab:

cd from-stuff
tar cf - . | (cd ../to-stuff; tar xvf -)

(Excerpt from "Running Linux" by Matt Welsh and Lar Kaufman, well worth
reading)

Check that everything you have in /usr, you have in /mnt/usr too.

In second phase you should edit your /etc/fstab to look like:

/                          hda        ext2      default     1 1
/usr                     hdb1        ext2      default     1 1
/mnt/cd                hdc        iso9660 ro,user    1 1

Reboot. The new filesystem is installed.
(You may have to do some symlinks to /usr tree anew)

Leave the hda as is. The second disk (hdb in my schema) could be used for
/usr as a whole. If it is about 1Gb drive you could add a generous swap
partition.
Check the du of your /home and /var trees, if you have many users.

>Are there certain problems with 2 HD's?????????????

No. I have 3 HD's + CD-ROM, all IDE.

You're welcome. All it takes is thinking. Draw a plan, make notes.
Don't Panic!     ;-)
