You can buy the seals between the front and rear windows from Toyota or Rare Spares at something like $33 each. Make sure you get them for each side as they are different. Un-screw the cover on the top back section behind each door, take out the retaining screw at the bottom of the rubber section, and slide each seal out. Re-fit is reversal of the above.
For your *armstrong* windows take off all the door trims and see why its so hard to wind up and down, then spray some CRC / WD40 on the moving bits to see if that fixes it.
