Here's what I remember...
Remember WAAAAAAAY back when 10.0 pretty much stunk the place up? And Apple said you could update to 10.1 but CompUSA was giving it away?
In order to use those disks, you needed 9.1 on the system (I had 8.6 at the time and needed 9.0 to get to 9.1). At any rate, it was more or less a HUGE patch.
Fast Forward about two years - Jaguar. I too received the free 10.2 CDs via the 'Teacher Promo' and those were FULL INSTALL CDs. Didn't need anything to put those baby's on.
I suspect that the up-to-date will be similar to the former - 10.2.x required to install 10.3.
However, since 10.2, OS X has played vary nice to home folders and apps with regards to 'clean installs' allowing you to wipe the thing clean save those folders.
