You don't delete the PCV, you just install the catch can in the PCV line. That way the PCV still operates to control the airflow through the engine. Yes they can help with build up on the valves, however with the mileage you list you might want to get the valves cleaned then see how much actual blowby you have. If they have never been done and the engine isn't using oil, you likely don't need one. Normally you only install them on known oil burners just to keep from building up carbon and to keep the converters alive.
As to how to set one up, you mount it with the top up, then run the in and out lines to go between the valve and intake manifold. In goes toward the PCV valve, out goes to the intake manifold.
