That's normal. Mine has had the same thing on several occasions of changing out the air filter. Just wipe it clean when changing the filter. No big deal.

Yup, a small amount of oil there is not unusual. The slight negative pressure in the air filter compartment sucks the crankcase vapors in through the breather tube (that's what it is supposed to do), and there is some oil mist in those vapors. The oil mist coalesces in the hose and filter compartment--over time you can find say a teaspoon or tablespoon or so of oil in the bottom of the air filter compartment.
