I received replies from the following individuals:
David Evans, Timothy Lorenc, Steve Hastings, Martin Baldenegro,
Andrew Petrov, and Allan West.
To each, I thank you.
Below is a summary of the answers I received, with the questions I asked.

The Ultra 1 internal bus is Single-ended.

It looks like just about any drive will probably work, but one would
have to be careful about the amount of generated heat. I think my
original thought will probably work best for me; 9 or 18GB 7200 RPM
drive, and I may decide to remove the current drive.
The answers I received on this were:
a. Look up the web for a master list of /etc/format.dat. This is the
file that the kernel uses to findout a drives ID and geometry. It's a
simple ASCII file so you can edit it yourself if you know what to do.
b. I have personally successfully used a Seagate 9.1 GB ST39102LC HDD
c. I am running 2 18gb single ended scsi Seagate 10k rpm cheetah
drives in 4 of my ultra 1's. The ultra 1's also use spud brackets to
mount the drives, but I have had problems with aftermarket ones and
would recommend going to sun for these, you won't regret the small
amount more to pay, verse the hasseles and I bought 2 dozen off brand
and returned them all they didn't work correctly in my d1000's.
d. I'm not sure what you can use 9 or 18 Gb drive as internal. That
way is not recommended because this drives are tend to overheating. I
use 4 Gb drive (Seagate) as internal and other (9 and 18 Gb) as
e. I'm using am 18GB Seagate drive from Bason in my personal Ultra-1. I removed
the original drive to lessen the effects of the bigger, hotter drive.
>3. Can anyone recommend a good CD-ROM drive model that will work
>internally, and boot my ultra-1?
Sounds like Toshiba is the winner here
The answers on this one were:
a. Any will do so long as you can set the jumpers to 512k blocks.
Most drives are set to 1024 or 2048 but can be set lower. Sun only
recognises 512 (unless something has changed recently).
b. Definitely use a Toshiba, I have a 40X SCSI in an Ultra1 because
the orig died
c. I use Tochiba CD-ROM drive in my Ultra 1
>4. Can anyone recommend some good vendors for the above mentioned
>parts, as well as mounting rails/hw for installation?
I'll just list the answers on this one. I'll be researching this one
a bit more to find the best prices.
a. *** www.solarsys.com for rails ***
*** www.fullerworkstations.com for rails ***
*** www.pricewatch.com for HDD and CD-ROM ***
b. Try www.solarsystems.com for the drives, and they can get you the
sun spud brackets cheaper than direct from sun. I think the drives
were 400-650 can't remember, been a while.
c. Bill at Bason can match you up with the right drive and also sell
you the "SPUD" bracket which makes it fit in Ultra- and
Bill Coffin is the knowledgable guy
