I am assuming they are the assembly that screws into the valve/cam cover and sits directly on the spark plug, with a molex style connector/wires coming from the harnes that runs parallel to the fuel rail. This right? its the 1.8 btw.
Yes, that's correct.

Also, the first cyclinder on the left, when looking at the motor from under the hood, had some oil on the piston and spark plug, the rest looked dry with some small specks of metal and some light tan deposits on the electrodes.
Considering the miles on your Sentra, it's normal, but you can fix that by replacing the valve cover gasket.

You can find more information on how to test the coils and injector in the "Engine Control" section of the service manual. You can download the section free from here: Knowledgebase - 2000 Sentra - Nissanhelp.com
