Kevin,
The door glass does require some finesse but patience is the key. I believe I started the vent frame in with the window down and rolled it up as I was sliding the vent frame down. I have done mine each twice ...they are not fun.
The windshield is the easiest to do. I sealed mine with butyl windshield sealer after I installed it (as I had leaks). I have never been able to do the rope trick. I just pull the rubber over the frame with my fingers and a pliers.
The rear window was the toughest for me. It took a lot of duct tape (holding the rubber on the glass) and the help of my 2 kids to have enough hands to get it in the frame. It just seamed that the rubber was impossible to handle. Installing the key is also tough but I sealed this window with silicone sealer.
Good luck
Rich
