Fairly easy with the right tools...
You need an 11mm socket on a swivel (or better yet a swivel socket!).
Pull off the door panel (duh!), and the rubber cap on the latch end. With a small flat blade screwdriver in hand, reach up into the cavity. Look down the hole uncovered by the end cap (you did put a trouble lamp in there already, right?). Flick up the latch on the plastic doohicky holding the rod to the handle. Now pull your hand out (you'll need it later) and get the socket on the swivel up in there. It only takes about 2 turns to run it all the way off.
Pull the handle out, and when the plastic latch doohicky gets to the edge, just wiggle it a bit to get it past the skin.
Replacement is more or less the above in reverse.
I just skinned and gutted both my doors. Cleaned every last bit of crud out of them, soaked the latches in solvent for an hour, etc and replaced my glass with new tinted stuff. Took about 6hrs for the first, and 2 for the second! Practice makes perfect!
