Jay, I did make the upgrade from Jag to Panther on the same setup you describe - iBook SE 366 / RAM maxed at 320 MB. Overall, I would estimate (I don't have any actual benchmarks) about 15-20% improvement in basic system & Finder speed. Not only do I notice the speed boost, but things seem to be smoother in operation. I don't run Photoshop on this machine, but Office & Acrobat are still a little slow to load (although scrolling through documents is a little quicker). I don't use this machine as my main workhorse (that's what my G4 iMac is for) & am very happy with what it is. I don't get the eye candy, but I don't really care about that stuff. It's a trade off I have accepted for ease of use & stability. My overall recommendation is this...if you are able to acquire it through an educational channel for $69, then it is a worthwhile upgrade from Jag. I don't know if I would drop the full upgrade price on it. If you are moving from OS9 & want to get into OSX, this is the upgrade you are looking for.
