Just in case you still want to know: You could glue foam panels to the inside of the door, but it would be better to just pressure fit them in place to avoid the weight of the glue. Any weight that you add to the door has the very real potential to unbalance the door. If the springs were a little "hot" or strong to start with, it may not be a bad thing to add weight. If the springs were the right ones, even a few pounds will un-balance the door. If they were too weak to start with, any additional weight is going to make it worse.
I'm not a professional, but I watched as my garage doors were serviced last year. The tech used a spray lubricant (I had bought a different brand in the garage door section of a home improvement store). He sprayed the inside of the entire track, top and bottom, the rollers that ride along the track, and all hinges on the door. He sprayed each hinge twice -- once on each side. The techs were more generous with the lubricant than I was when I'd done it before, so don't be afraid to give it a good squirt.
