R3aper

I have an Atari 2600 Jr (long rainbow, board revision D) which I have owned since I was a kid. The main capacitor was leaking, and all of the switches needed to be cleaned up. While I was in there I decided to fix up some of the other components as well. I ordered an "Atari 2600 4-switch/Jr refresh kit" from Console5.com and started replacing some of the parts. So far I have the large 2200uF 16v capacitor replaced, as well as the 4.7uF 35v capacitor next to the video jack. I also replaced the video jack and voltage regulator, and made a high quality cable from RG6 and an F-type to RCA adapter. My Atari works pretty good now but I still have some leftover parts and I can't figure out where they would go, or if they even apply to my board revision. There were four 4.7uF capacitors in the kit but I could only find one on my board. There are also two small square parts (capacitors?) made of hard plastic labeled ".22K100", and two small capacitors about the size of a small resistor labeled "K5G 821K". I can't find anything with similar markings on the board. Most of the part labels are printed underneath the parts on the board, which makes them hard to identify. I have attached pictures of my board and the parts. Does anyone know if these parts would apply to my board?
