This will certainly lead you into the dark area of fixing a load of JS 
problems :-(

No, but it will fix the click events. It may however introduce new 
issues as side effect.

Well, part of the "bring-jQuery-into-the-core" process should have been 
to rewrite the code that relied on prototype / scriptaculous and drop 
those libraries. Ideally ExtJS stuff should be moved to jQuery too 
(except probably the nice ExtDirect handling).

If you can migrate it to jQuery it will be a step forward. Otherwise 
fixing the clickevents would be my number two choice.
