No worries. Heck I don't know much about sedan rear doors honestly. I've been into them plenty but my 97-03 GP experience is mainly with coupes. This Dorman instruction page for coupes differs from our cars only in removing the trim panel, the rest is similar or same although you are working on a rear door. I recommend replacing the reguator and motor assembly in the case of trouble with either.

Since you have door panels off already, its cake. Use some tape to hold the glass up if the seal does not do that, unplug motor, unbolt glass, motor, regulator and remove. Reverse to install. Yes its all floppy but just be gentle when bending the cables as you install the new part.
If a jammed regulator's current position can't be changed to align with the window bolt holes in the door shell, it will just be harder to unbolt the glass. In this case, the regulator can be unbolted first to relieve tension holding the glass up. Also, lots of parts stores carry replacement clips for the door trim panel but they may be longer. In my experience, the longer ones can rub the glass if installed on the top row. So maybe snip the tips off any longer replacement clips if needed there.
