I am having the same issue as you did. Im on 10.6.8 on a lat 2010 MacMini.
I started having an issue with my Time Machine backups. I tried to fix but it wasnt backing up stuff on my backup drive.
Then all icons disappeared from desktop and realized that this was due to Finder.app, so I trashed the finder.app com.plist and thought it would fix it, but it did not.
Then I found a fix and punched in a command in Terminal and that took care of it, and all my icons appeared back on my desktop. Thus, I rebooted, but have never been able to log back on in my computer...none of the Startup key combos work, I cannot even get the DVD 10.6.to install! Thus I no longer have a computer and am stuck to using my old G4 laptop!
I have no idea what happened, but months ago I realzied I could not copy or create DVDs, so I went back to the Genius store and they told me to buy a new optical drive. They didnt look at my computer, but said what I described was that my optical drive was dead. Now, I dont know why but is this why I can no longer reboot, or get my computer to start up? Can't seem to get past the blue screen.
Im hoping there is a superuser out there, a technically savvy individual who can give me a script to by pass the Finder.app, or replace it.
Im also thinking that maybe just ugrading to Snow Lion might help?
PSS What did you do to log in? From your post, you could not start up from the install DVD either?
Thanks!

All is well. Boots up and logs in. It was because of the lion files from my time machine. Now I'm installing lion and will then restore from backup from the built in lion recovery partition
