Which dust filter should I purchase for 98 E320 and how many?

I really appreciate all the help I am receiving. I am in the process of ordering all the parts necessary for a FSS B for a 98 E320(V6). My question concerns the dust filter behind the glove compartment. Do I order two or one of the "Dust Filter 210 830 10 18 $32.43" from PartsShop or does it come with the necessary filters? Or do I need to order the Charcoal filter? I see on the climate control the button that I keep down which I believe is some type of charcoal filter. In addition are these the parts I should order:
Air Filter 604 694 0504 $25.71
Oil Filter 112 180 00 09 $10.49
9 quarts of Mobil 10w30 oil
