i can confirm the above statement. there are 2 plugs and not 3. the 2 plugs require the same bit size to unscrew. dont touch the black rubber thing in between the two plugs. thats just the jacking point.
dont worry too much bout the little bit of oil thats on the pan. i believe my car has some residue like that as well. i think its probably due to the expansion and contraction of the metal oil pan and drain plug that causes a slight leak. you shouldnt see any oil dripping though. if you do, then you have a problem.
