SuperDuper, which is a very good app, makes a clone of your hard drive which, in your case, means it has a clone of the "Flaky Install"
Personally I would go with Time Machine, and SuperDuper, as this will give you the flexibility that SD does not give by itself.
Time Machine will allow you to reinstall those non-Apple apps, and the data that goes along with them, after you have installed OS X again.
In the absence of a TM backup, you would need to backup all the data that was created and save it else where until you have installed, from their original sources, all the non-Apple apps.
You may also have a permissions problem if the data you are trying to recover was created by the original Main User.
On that subject, the recommended number of accounts is two. One Admin and one Non-Admin that is used as the main account on the machine. It's a security thing.

Hi all. iMac (2.11, 2010 vintage) i3 3.06 ghz, 8 gig RAM, OS 10.6.8.
I'm tired of the flaky install on this computer,and want to wipe the system drive,re-install the OS, my apps and data.
System drive is backed up completely (via SuperDuper). I'm clear on how to wipe and re-install the OS and the bundled apps that came with the iMac (I have the original drives and know where the 10.6.8 update resides on Apple's website).
HOWEVER...I have lots of other non-Apple apps, and the data that goes along with them. (Let me mention here that I'm changing the OS install slightly, and only creating one user, who will be the Admin as well...this differs from the current install, which features a separate [main] User and Admin). Am I going to have to install all these apps from their original sources? Any suggestions on helping that process along?
