The glass isn't hard at all if you're patient. Swapping doors to me is a total pain in the butt, what with all the alignment and all, depending how you do it.
You remove the interior handle, remove the door panel, be careful prying out the clips. Raise the window up until you have access to the two bolts Priya was talking about. The nuts are enclosed in plastic bow-tie looking pieces that will inevitably spin, so you have to squeeze a hand behind the glass with a wrench to hold them still. You will be able to fit a 1/2" or so wrench over them in back but it can slip off easily. Once those two bolts are out, the glass is free from the regulator and can be pulled up and out. You may have to tilt it as it comes up. Great time to door new glass channels and sweeps, since you must remove the glass to do those and they're typically cracked after 30 years.
To do a door handle, you need a Torx driver. Remove the door panel as mentioned above, but just raise the glass with the crank up out of your way. Disconnect the linkage to the door handle and remove the two Torx screws. Pop the handle out. Keep the gasket and re-use it. They are still available if needed.
If you're planning a custom paint job, you'll want all this removed to do it right anyway.
