A bad ignition coil would not cause your oil consumption. A misfire, hard starting and fouled plugs are symptoms of a faulty coil. There are simple tests you can do at home to check your coils and plug wires using a volt meter (see a Haynes Subaru Manual). Some autoparts stores will test them for free if you bring it in to them.

Unless your have a bad running engine, thowing codes I doubt it.
A bad coil should result in a misfire code.
A bad coil pack that resulted no spark to a cylinder could result in unburned fuel dilluting the oil, causing abnormal wear, leading to oil burning.

The piston rings or valve seals will deal with the oil problem. You could try changing the PCV valve again to see if that helps.

The misfire could be due to a bad plugwire or plug. If you have a throttle position sensor then check that for a dirty contact wiper. I doubt that the coil is causing these problems.
