I've noticed on the drivers and passenger windows an after market tint has been applied to the windows. I offer that as a possible additional source of drag. Is there any kind of lubricant (spray Silicone for ex.) that can be applied to the rubber door gaskets or brushes to facilitate a smoother roll up? Or do the motors just need replacing due to 16 years of service?

Try a silicone spray. Spray it into the channels where the window glass rides. after spraying, operate the window a few times and repeat until the window works better.
