Your PCV is built into the valve cover so the new cover you bought gives you a brand new PCV along with that.
How do you mean the plugs were soiled? Just black soot? Do you see oil on them? White residue? There are many different symptoms and causes.
Also, there are some gaskets around the spark plug tubes under the valve cover. I'd replace those too. If these gaskets dry out and leak you'll have oil around your spark plugs.
FYI: Some symptoms of a failed PCV (pulled it off a random page via a quick google search)
a rise in the pressure of the internal engine
failure of seal/gasket
leaking oil from the engine
emission of black smoke
construction of the sludge under the hood
wetness under your hood
engine surge
frequent lean fire
oil discovered in the maf sensor
increased oil consumption rate
