1. Yes get a filter.
2. Replace the valve cover to filter hose with the correct one.
3. Get 3 new mounts

And heat shields to protect them.

4. While you have the filter out replace the oil separator drain tube Orings. Call Phil for those, there are 2 one at the top of the drain tube and one at the bottom.
I find it easier to remove the air filter by open it up, remove the filter, unbolt the 3 nuts in the bottom of the filter housing, then unclamp the U shaped duct (It goes from the filter housing to the turbo) at the turbo. Check the large flat Oring seals in the large U duct.
5. Check the air filter mount to make sure it is not cracked, If it is, either weld it or replace it.

Once the filter housing is done you will probably get some oil in the filter but only inside the filter ( filtered air side) not on the outside ( fresh air side). This is common. If it is excessive then post the problem, there are quite a few things to look at.

Other things I notice. Oil filler cap is bad, get a new one, it helps keep the engine clean. Valve cover gasket leaking, consider a valve adjustment and new gasket. Clean the engine, I use an engine degreaser and fresh water, the water will not hurt the engine ( As long as cool, not on a hot engine). I will use my high pressure washer on the engine. And of course keep reading here and you will figure out all sorts of things to do to the car.
