A Foot Each In Leopard & Lion - 1st few problems :
When my late `06 iMac went basically kaput, I went to booting off an external clone of it's entire 600+ gb's from an `06 MacBook . . .
( never knew so much beach-ball and force quits were possible ! )
Dear friends in Austin bought and just sent me a used 2009 21.5" on 10.7.5 ( 3.06 GHz Core 2 Duo / 4 GB 1067 MHz RAM ) . .  and it has 487.01 free out of 499.25 GB.
I'm not diving head-first into Lion ( it seems I've heard more problematic tales on that OS then others, maybe ? ), so until I figure out how to enjoy my 600+ GBs on a "new" 499 GB, I'm booting the "new" one off the same external with everything amassed up thru now.
I indeed get confused about which HD is "in charge" . . .
Leopard's on the external, but it's being processed thru Lion, kind'a ? . . . right ?!
That would suggest many things need to be reconciled :
I first noticed Quicktime Pro couldn't play mp4s of 1080 movie burns.
Audio plays . .  picture's black !
That was my first question.
Then, a simple Control/Shift/3 screen-shot came out completely scrambled . .  everytime !
Then things got deeper !!
A simple "oh good, iTunes isn't detecting my iPod . .  let's try a restart" resulted in the infamous "your computer needs to be restarted, please hold the power button for several seconds . . ." descending kernel panic screen !!
More attempts got lesser results, up to no gearwheel at all on unchanging gray screen. . .  till I let it be awhile and got back to the kernel screen.
12 hours later it just let me boot to the internal HD with Lion.
But I felt a run of Disk Warrior was still in order . .
I get :
"DiskWarrior cannot currently be run from this disk because Mac OS X ignores ownership of some disks by default . . ."
it suggest an approach which ends with :
3) Click the "Sharing & permissions" triangle
4) Uncheck "Ignore ownership on this volume"
This becomes a ring of Catch 22 till my head hurts !!
Right now, I can't even find an icon of the volume for Get Info, but when I saw it yesterday, it said under "Sharing & permissions" that I have "custom access' !?
When I spoke to the wife of the wonderful couple who sent me this, she said she had indeed entered my name as admin, but there was "no password".
Well Finder sure seems to know about & want one !!
How do accomplish any changes without knowing what it is ???
It's a wee bit difficult to know what my questions actually are when this confused halfway thru the looking glass . . .
And no, outside of the 2009 iMac, & a wireless mouse and keyboard not recognized when booted to Leopard, there was no Install Disc sent.

Answer 1

Alright, . . . 
I feel for anybody try'na sort thru my nonsense here, so let me eliminate things that have "improved" :
The "new" Mac calmed down, became bootable. And once Spotlight finished 90 minutes on indexing the prime external I was able to boot from it again. ( It's where all my apps are afterall, and a terrain I don't have to learn for days to use yet )
On 1st restart option, the external didn't show, but that cleared-up, and I ran Disk Warrior
the reults --
DiskWarrior has successfully built a new optimized directory for the disk named "Macintosh HD." The new directory is ready to replace the original directory.
All file and folder data was easily located.
Comparison of the original and replacement directories indicates that there will be changes to the number, the
contents and/or the attributes of the files and folders. It is recommended that you preview the replacement
directory and examine the items listed below. All files and folders were compared and a total of 7,622,306
comparison tests were performed.
• Errors, if any, in the directory structure such as tree depth, header node, map nodes, node size, node counts, node
links, indexes and more have been repaired.
• 13 files had a directory entry with an incorrect text encoding value that was repaired.
• Critical values in the Volume Information were incorrect and were repaired.
• 1 folder will have more items.
• 2 files had a Name that changed.
