Maintenance questions

So I figured from looking at the e38.org page I can do the fuel filter, the spark plugs & the cabin filters pretty easily. Heres a few links to the parts Im considering. Are these all ok to use? Is the fuel filter as straight forward as it looks on e38.org?

I can tell you that those three items are about the easiest things to change in these cars. The fuel filter is under the plastic cover next to the gas tank, the cabin filters are on the rear of the hood, held on by one screw each, and the spark plugs are under the coil packs, under the plastic covers. The only thing I can tell you about replacement parts is that these cars are picky, so try to stick to OEM if possible, especially on suspension and electronic parts. The first two links seem to be OEM parts, but I wouldn't put 4 prong plugs in any motor because I believe they are trash. You should get the two prong plugs that came with your car, or do what I did and go with iridiums.

Anyone have a part # for the plugs I should use?
