You're most welcome, Doug.
Thank you, but I do not want any money. As explained here, I am a user like you posting here to help other Apple users: http://discussions.apple.com/static/apple/tutorial/etiquette.html
Here are my responses to the new information and questions you have posted.

I am happy you found out how to make your keyboard work. I expect that means there is nothing wrong with the backlight hardware so you are wise to now concentrate on proper iSight operation. The suggestions in
http://support.apple.com/kb/HT2090 will be your best hope.
ddabarqu wrote: ... Is it possible to redownload the combo update again and do the process all over again?
Yes. All you need to do is to restart your Mac and then follow the steps I posted, beginning and ending with permissions repair.
ddabarqu wrote: ... Do you know by any chance if this will work this time?
No, I do not know. The only way to know whether it will work is to try it.
The good part of this is that it costs nothing except a few minutes of your time to find out whether the Combo Update will fix your problem. If it does not help, it cannot harm anything.

Unless you have a current backup, make one now!
You can make as many backups as you like after you have reformatted your Mac, but, unless it is already backed up, all your information will be lost when you erase and resinstall. Therefore, you need to have your important info backed up BEFORE erasing.

After you backup your important information, reformatting and reinstalling everything cannot hurt your Mac. However, it takes MUCH longer than simply applying the Combo Update. That is why I recommend trying the Combo first.
I do not know whether erase and reinstall will work. The only way to know whether it will work is to try it. As noted above, you may be able to save time if the Combo works without reformatting.
I do know that you can use the method I suggested to apply or reapply the latest Combo Update for your Mac OS at any time.
The only way I would recommend formatting without trying the Combo firstis if you have moved, deleted, modified, or added third-party software you believe is conflicting with your current Mac OS. If you have been unable to uninstall, correct, or undo changes you have made to your system, reformatting (using a Secure Erase) and reinstalling everything would be a better choice than trying the Combo Update.
If you decide to Secure Erase, writing zeros one time will probably take a couple of hours. There is no need to wait the additional time required for writing multiple zero passes.

Yes, your iSight's serial number looks strange to me, too. However, I doubt that your iSight S/N determines whether your iSight works. If it you cannot get your iSight working using these suggestions, you can ask your Apple Service Technician if your S/N might be part of the problem.
