To replace, first remove the old filter, which can be accessed by removing the top shelf. Pull it down and turn counter-clockwise to remove. Take your new filter and check to make sure the tabs are in the horizontal position. Now push it into the compartment and rotate it until it is secure. To remove trapped air, run 2.5 gallons of water through the system in cycles of 30 seconds on and 60 second off. If your model has an indicator on the display, push and hold the Filter or Reset button for about 5 seconds to reset.

The ice tray had warped and dumped water, which then froze down through the ice bucket and below.

To replace the warped tray, I found the service manual (pg. 124 below) which took some interpreting.
Removed the lever. Then removed the assembly by two screws that are forward to the unit and go upwards.
The insulation, sensor, and sensor cover are simply pulled down and off and the unit separated to removed the tray, and then insert the new tray. Proceed in reverse. Takes only a few minutes.

Broken Guide Rail

This site was awesome! I was able to very quickly look up my refrigerator model, find the proper part number, and order the part. The only suggestion I would make is to update the cut sheet with a more clear version, it was a little difficult to make out the part number because the scan/drawing was fuzzy, but I was still able to make it out. Got the part in the mail very quickly and it was super easy to remove the old rail and install the new one. Take out the screws from the old one, remove the old rail, line up the holes, install the new one, and put back the screws. It's so nice to have a site like this to fine parts and order them! Too cool! Thank you so much!
