They're quite easy to fit when all is said and done, but frustrations run high.
I've just done all 4 doors
A very quick run down went something like (the haynes manual is fairly good for the info):
Remove all the interior trim from the door, including the protecting poythene/foam.
Remove the exterior door handle.
Remove the old vacuum pump/lock (3 star bolts on the lip of the door, below the one that holds the handle on).
Re-Use the rods from the old pump/lock.
You may have to un-bolt part of the window holding mechanism (a large brace with 2 bolts, one at top of the door one at the bottom) to get the pump into position.
Getting the pump into its place is the hardest part (you may wish to wear hand protection depending on how sharp your door edges are - old doors from the '97 nice and soft - replacement doors from a '94 somewhat sharp)
Once you have it in place (worst part getting the push-pin interior locks rod up the hole of the door) just bolt in, hook up the pipes/cables, bolt in the exterior door handle, re-fit the trim, etc etc etc.
