It should be fairly obvious what plug to remove. If there is any doubt, you should d/l the shop manual online from Tone Monday's web site.

If you buy anything, I would agree with Ruflyf. A good quality breaker bar is not very expensive and will come in handy time and time again. I would get a 1/2" drive and a socket to fit your oil pan plug (I think it's 22 mm). You'd be surprised what another 4-6" of leverage will do for getting a tough bolt out. BIG difference!
