There are 8 spark plugs and coils on the '01 V8 and 6 on the V6; for future reference, the engine type (V-6 or V-8) tells you how many spark plugs and coils are equipped.
If you are talking about oil on the outside of the spark plug then you have a leaking valve cover gasket. Oil on the spark plug electrode is a sign of defective rings and an engine in need of an overhaul.

Yes, a bad coil will affect any combination or all of the cylinders - it is the source of all spark required for firing the spark plugs and making the engine run.
You can remove the motor mount and roll the engine froward or get an socket wrench and a long extension and spark plug socket will do the trick very tight squeeze but is possible with out removing anything at all
check/replace spark plugs and wires
