I've never done the valve cover gaskets, so can't say.
The PCV is very easy. You already have the engine cover off, so find the vacuum line that comes off the TB with the white check valve in it, and just follow it back under the manifold.
You want to make sure that the vacuum lines themselves are in good shape with no holes. If they are even remotely brittle, just replace them. In fact have some vacuum line on hand as there is a good chance the line where it joins the separator will be in rough shape.
You will also want to make sure that the check valve is working (air should only go through it one way) and that its installed in the correct orientation (flow towards the TB).
When you get the hose off the nipple on the oil separator, you will need a thin probe to make sure the small opening in the center of the nipple is clear. I use an old broken drill bit -- its long and thin enough and the chuck end give me enough to hold onto to clear the hole out.
This simple act slowed down or stopped a fair amount of seepage be restoring the slight crankcase vacuum.
