just put one on my car last week, pretty simple install. the hose going in to the turbo inlet pipe can be plugged with just a regular bolt, i think its a M14-1.50 Picked it up a local hardware store. as for the hose on the throttle body, get some 4mm aka 5/32" vacuum hose caps found at most auto shops.
I would advise against modding the T5 PCV system for the following reasons. You need the vacuum to purge the crankcase of blowby gasses which contain potentialy sludge forming acidic contaminants. Although a small quantity of oil may be passed to the intake the vast majority of oil contamination comes from the turbo seals which are impossible to make oil tight.
