So you got a blind powerbook and a powerbook that refuses to wake up. Talk about computers with personality. 
For the Wallstreet, If you haven't already tried maybe you could take a screwdriver and a small hammer and gently yet firmly pound the screwdriver into the screw. taking it slowly and making sure not to do it too hard. This should help make an impression of the screwdriver so you have something for the screwdriver to catch. Wait for a second opinion before trying this though.... In case there is a reason for NOT doing this.
As for the Lombard, sounds like a real puzzler. However, since I own a Lombard myself I may be able to give a few hints.
First, in my experience with the Lombard, if you want to read a CD, use a CD drive, if a DVD, a DVD drive. I own both a CD and DVD drive for the Lombard. (Though the DVD drive died a few months back.) Whenever I wanted to use a CD or DVD I would always have to switch out the drives. I have no idea why, the DVD drive just didn't like most CDs. You might have to get a regular CD drive before you can boot from a CD. Might just be a Lombard thing.
As for the hard drive, I haven't got a clue... Maybe when you get the CD boot issue fixed you'll be able to format the HD and install Mac OS 9 from the Lombard.
Good luck to you and your friend!
