Oil around spark-plug wire, Cause to be concerned? Options

[solidxsnake]

At some point in the near future I intend on replacing my plugs, wires, rotor, cap and doing an oil change. Since I'm completely unfamiliar with doing simple maintenance such as that, I decided to run through a couple steps out of curiosity.

I came across a lot of oil being around the rubber seal on the first cylinder's plug wire, the one on the top of the head. None of the other seals had oil on them, so I'm led to believe that there's a leak somewhere that I should get checked out. As for burning oil, the engine doesn't burn oil normally (nearing 174k miles), but at startup until it warms up it puffs thin white smoke with a tinge of blue for a couple of minutes. I know that's relatively normal, but I'm not sure about the oil around the spark plug wire. Should I be concerned? And what are possible causes/fixes for the leak (for instance, where would the leak be? Obviously somewhere in the head around that plug hole).

Thank you
