Bottom line - I have my disk back. I post the steps I took below for others to read. Please comment / change anything which I may have not explained correctly. I wanted to be a little more verbose in case others had a similar issue so I have had to post this in two separate postings. Many thanks to you and the folks at PGP for your assistance.
1) After your previous post I put the laptop in Target Disk mode and connected it via firewire to the other Laptop with PGP installed.
2) Upon opening a Terminal session it was clear that the disk was not repaired as the hexdump -C -n 128 /dev/rdisk1 and hexdump -C -n 128 /dev/disk1 commands did NOT show PGPGUARD as shown here:
Musashi:~ go$ diskutil list

3) I then ran the following commands you provided in a previous post:
Musashi:~ go$ pgpwde --disk 1 --recover --passphrase
Searching disk for PGP WDE signature
112304128 sectors searched, 512838320 sectors to go

Recovery successful!
No bootable volumes found. Checks complete.

Musashi:~ go$ pgpwde --disk 1 --auth-disk --passphrase
4) If the --auth-disk command worked, the suggestion was to then use unmountdisk disk1 and then try and mount the disk using mountdisk disk1
5) The trouble was that, for whatever reason, each time the "unmountdisk" command was used - it worked - BUT it also erased / removed the PGPGUARD information located by the --recover command and synced using "sync".
6) Instead, after the successful --auth-disk command above, I started DISK WARRIOR (which was installed on the laptop where I was running the pgpwde commands) and it found the disk (previously it had been able to find the disk but could NOT optimize and rebuild the directory as it was unable to access a non-authenticated disk).
7) After running DISK WARRIOR it created a replacement directory which could NOT be compared to the original as the original was too severely damaged. I previewed the new directory and decided to use it to replace the damaged one.
8) After installing the new directory - voila - disk1 and all its volumes would mount and unmount (I had fun playing with this several times). As you can see below - disk1s2 no longer had a garbled name but showed "Macintosh HD" instead (which was the disk name).
Musashi:~ go$ diskutil list

Musashi:~ go$ diskutil mountdisk disk1
Volume(s) mounted successfully
Musashi:~ go$ diskutil unmountdisk disk1
Unmount of all volumes on disk1 was successful
Musashi:~ go$ diskutil mountdisk disk1
Volume(s) mounted successfully
Musashi:~ go$ diskutil unmountdisk disk1
Unmount of all volumes on disk1 was successful
9) I then shut everything down, and tried to boot the laptop - no go - still got the spinning wheel then the "no go" icon.
10) I reconnected everything, put the laptop in Target mode again - and it popped up on the desktop and requested my PGP Passphrase. (A good sign). I entered the passphrase and disk1 mounted on the desktop (wow- two good signs).
11) After that I entered another Terminal session and - after checking to ensure the disk status showed disk1 as being instrumented by Bootguard, I started the --decrypt command. It took about 16 hours to decrypt.
12) I unmounted the disk, unplugged the firewire cable and tried to boot the laptop. Success! I chose to use Disk Warrior again to clean up the multitude of permission errors. I still have problems updating some minor programs but the data is all there.
I wrote all this out so others would know what I did. I can't thank you enough for all your efforts as it was your research that lead to the recovery of the disk. Many thanks for the great support from PGP!
