PCV valve is right on top of the intake manifold on the driver's side about 2/3 of the way toward the back of the engine. There's a hose that's about 1/2" diameter I think. If you have a replacement PCV you'll be able to identify it pretty easily.

For other things, you should probably replace all the driveline fluids, lube the front driveshaft, drain and fill the coolant system, and maybe repack front wheel bearings within the next 10K miles.
